Hi GAP team, On Ubuntu 20.04.3 LTS, I'm using the latest self-compiled git master version of GAP, and I noticed the following command has been implemented:
================= gap> ??ColorGroup > ColorGroup( <G>, <H> ) > F constructs a colored copy of <G>, with color subgroup <H> (which should have finite index in <G>). Color groups constructed in this way are always their own parent. It is not possible to set their parent attribute to a different value. Groups which may be colored include, in particular, `AffineCrystGroups', but coloring of any finite group should work as well. ================= But I can't find any explanation for this command in the GAP - Reference Manual [1]. OTOH, I want to know if this command can be used to create all the Magnetic space group as describe here [2]. Any tips will be appreciated.
