Does anyone know how this function is supposed to work? it is one of the CAS functions introduced in the latest update. The release notes do not explain it and Help just says it tests whether a permutation is a cycle. The functions cycle2perm and permu2cycles work as described here but is_cycle seems to return 1 for any permutation whether cyclic or not.
TIA,
John
