MaximalSubgroupsRepresentatives( S, "translationEqual", [, ind ] )
MaximalSubgroupsRepresentatives( S, "classEqual", ind )
MaximalSubgroupsRepresentatives( S, ind )
returns a list of conjugacy class representatives of maximal subgroups of the CrystGroup S. If ind is present, which must be a prime or a list of primes, only those subgroups are returned whose index is a power of a prime contained in or equal to ind. If the flag ``translationEqual" is present, only those subgroups are returned which are translation-equal (translationengleich) with S. If the flag ``classEqual" is present, only those subgroups are return which are class-equal (klassengleich) with S. ind is optional only if the flag ``latticeEqual" is present. In all other cases, ind is required.
