Some Results on Derivation Groups
Murat Alp · DergiPark (Istanbul University) · 2000
In this paper we describe a share package XMOD of functions for computing with finite, permutation crossed modules, their morphisms and derivations; cat1-groups, their morphisms and their sections, written using the GAP \\cite{GAP} group theory programming language. We also give some mathematical results for derivations. These results are suggested by the output produced by the XMOD package.
