There are particularly efficient methods for finitely presented semigroups and monoids, and for semigroups and monoids consisting of transformations, partial permutations, bipartitions, partitioned binary relations, subsemigroups of regular Rees 0-matrix semigroups, and matrices of various semirings including boolean matrices, matrices over finite fields, and certain tropical matrices. Semigroups contains efficient methods for creating semigroups, monoids, and inverse semigroups and monoids, calculating their Green's structure, ideals, size, elements, group of units, small generating sets, testing membership, finding the inverses of a regular element, factorizing elements over the generators, and so on. It is possible to test if a semigroup satisfies a particular property, such as if it is regular, simple, inverse, completely regular, and a large number of further properties. There are methods for finding presentations for a semigroup, the congruences of a semigroup, the maximal subsemigroups of a finite semigroup, smaller degree partial permutation representations, and the character tables of inverse semigroups. There are functions for producing pictures of the Green's structure of a semigroup, and for drawing graphical representations of certain types of elements."},"rdependencies":[{"block":false,"categoryid":1562,"description":"Collection of standard data structures for GAP","ebuildids":[859390,874425],"firstseen":"2024-01-22T11:43:13.819329","name":"datastructures","packageid":76989,"summary":"The datastructures package aims at providing standard datastructures, consolidating existing code and improving on it, in particular in view of HPC-GAP.

This enables easy exchangability of implementations, for example for more efficient implementations, or implementations more suited for parallelisation or sequential use.
