Dear Benjamin Sambale, Thank you very much for reporting this bug. It will be corrected in the next release.
> What is wrong here? (I know that StructureDescription is of little use here > anyway.) The library code for working with PCGS for permutation groups assumed that the PCGS (policyclic generating set) for a new group has an entry permpcgsNormalSteps, indicating how the pcgs fits to an elementary abelian series. This is not true for PCGS created by the package `crisp' and the library code therefore needs to check for this property. (Starting GAP without loading the package ``crisp'' thus is a tremporary workaround.)
