If the optional second argument n is not present, then the degree of f is used by defualt. When the arguments are a transformation f , a positive integer n , and true , KernelOfTransformation returns the kernel of the transformation f on [ If the argument bool is false , then only the non-singleton classes are returned. The second and third arguments are optional, the default values are the degree of f and true. InverseOfTransformation returns a semigroup inverse of the transformation f in the full transformation semigroup.

Every transformation has at least one inverse. If f is not a bijection, then fail is returned. The smallest idempotent power of f is the least multiple of the period of f that is greater than or equal to the index of f ; see IndexPeriodOfTransformation ComponentsOfTransformation returns a list of the components of the transformation f. Each component is a subset of [ DegreeOfTransformation f ] , and the union of the components is [ DegreeOfTransformation f ]. NrComponentsOfTransformation returns the number of components of the transformation f on the range [ ComponentRepsOfTransformation returns the representatives, in the following sense, of the components of the transformation f.

For every i in [ The representatives returned by ComponentRepsOfTransformation are partitioned according to the component they belong to. ComponentRepsOfTransformation returns the least number of representatives. When the arguments of this function are a transformation f and a list list , it returns a list of the cycles of the components of f containing any element of list. If the optional second argument is not present, then the range [ DegreeOfTransformation f ] is used as the default value for list.

If f is a transformation and n is a positive integer, then CycleTransformationInt returns the cycle of the component of f containing n. It can happen that the internal representation of a transformation uses more memory than necessary. For example, this can happen when composing transformations where it is possible that the resulting transformation f belongs to IsTrans4Rep and stores its images as bit integers, while none of its moved points exceeds The purpose of TrimTransformation is to change the internal representation of such an f to remove the trailing fixed points in the internal representation of f.

If the optional second argument n is provided, then the internal representation of f is reduced to the images of the first n positive integers. If the optional second argument is not included, then the degree of f is used by default. The transformation f is changed in-place, and nothing is returned by this function. If f is a transformation where the degree n of f exceeds the value of the user preference TransformationDisplayLimit , then f is displayed as:. The idea is to abbreviate the display of transformations defined on many points.

The default value for the TransformationDisplayLimit is If the degree of f does not exceed the value of TransformationDisplayLimit , then how f is displayed depends on the value of the user preference NotationForTransformations. With this option a transformation f is displayed in as: Transformation ImageListOfTransformation f , n where n is the degree of f. The only exception is the identity transformation, which is displayed as: IdentityTransformation. As mentioned at the start of the chapter, every semigroup is isomorphic to a semigroup of transformations, and in this section we describe the functions in GAP specific to transformation semigroups.

For more information about semigroups in general see Chapter The Semigroups package contains many additional functions and methods for computing with semigroups of transformations.

In particular, Semigroups contains more efficient methods than those available in the GAP library and in many cases more efficient than any other software for creating semigroups of transformations, calculating their Green's classes, size, elements, group of units, minimal ideal, small generating sets, testing membership, finding the inverses of a regular element, factorizing elements over the generators, and more. Since a transformation semigroup is also a transformation collection, there are special methods for MovedPoints A transformation semigroup is simply a semigroup consisting of transformations.

A transformation monoid is a monoid consisting of transformations. Note that it is possible for a transformation semigroup to have a multiplicative neutral element i.

### Key Concepts

For example,. In this example S cannot be converted into a monoid using AsMonoid For more details see IsMagmaWithOne The degree of a transformation semigroup S is just the maximum of the degrees of the elements of S. If n is a positive integer, then FullTransformationSemigroup returns the monoid consisting of all transformations with degree at most n , called the full transformation semigroup.

If the transformation semigroup S of degree n contains every transformation of degree at most n , then IsFullTransformationSemigroup returns true and otherwise it returns false. It is common in the literature for the full transformation monoid to be referred to as the full transformation semigroup. Returns an isomorphism from the finite semigroup S to a transformation semigroup.

For most types of objects in GAP the degree of this transformation semigroup will be equal to the size of S plus 1. The isomorphism from S to the transformation semigroup described in this way is called the right regular representation of S. In most cases, IsomorphismTransformationSemigroup will return the right regular representation of S. As exceptions, if S is a permutation group or a partial perm semigroup, then the elements of S act naturally and faithfully by transformations on the values from 1 to the largest moved point of S. If S is a finitely presented semigroup, then the Todd-Coxeter approach will be attempted.

Watch a webinar series hosted by the Transformations Knowledge-Action Network exploring research on social transformations to sustainability. All images selected for the various exhibitions will be represented in specially created on-line galleries. The gallery will be hosted and promoted on the PCP website for at least two months following the close of the show. All physical artwork must be available for sale. We expect that this will be a visually stunning show with excellent sales potential for the participants.

To maximize that potential, everyone accepted into the exhibition will be offered the opportunity to bring two unframed images for display in our print bins. Successful entrants for the Digital and Unlimited Exhibition will be afforded the same opportunity, but please note that the prints will need to be dropped off and picked up in accordance with the same schedule that applies to print entrants. Size and display requirements will be provided to artists accepted into the exhibition.

If you would like to enter images for jurying in more than one of the exhibition categories, you may do so. However, separate applications and entry fees apply. Entry fees are non-refundable. Again, this is a competitive, juried show and entering does not guarantee acceptance.

We use a very easy-to-navigate entry program that allows entrants to change or add images up to the deadline. The software system that we are using requires payment as the step prior to the actual submission of images on the application form. The benefit of this system is that we can now allow you to add as many additional images as you want, at the discounted rate — whenever you want.

## OpenSCAD User Manual/Transformations

You may also replace an entered image with a new image or an improved version of the original. The Judge will select images for 1 st , 2 nd , and one or more Honorable Mention awards in each of the Print, Digital, and Unlimited competitions. Additional awards may be added and prizes will vary dependent on sponsorship. October 27, Sat.

Days and Times TBD. November 19, PM.

The PCP reserves the right to alter dates to accommodate situations beyond our control. Frameless, hard surface professionally mounted images are acceptable, such as images on acrylic or aluminum. No unframed foam core or similar mounted prints will be admitted. Note on canvas prints: Canvas prints generally do not display well when shown alongside professional level paper, acrylic, or metal prints and will not be accepted to protect the integrity of the show. All artwork must be ready to securely hang with hanging wires installed. The PCP reserves the right to and will reject any submission that does not meet those standards.
