Dear Martin, thank you for giving me the definition of cycles and linear order, this enabled me to do some more tests. I tried to generate the isomorphism type series of permutation and an error occured. May you take a look on http://axiom-wiki.newsynthesis.org/SandBoxSpeciesBayreuth2
Also [structures(labels3)LatexWiki ImageACLIST(Graph(Z)) leads to an error.
