I have tried to calculate maximal subgroups of symmetric groups
using MaximalSubgroups in GAP 3.4.4.
This was successfull for all n not greater then 8, but for n=9
I obtain the following message:
Error, sorry, can' t identify the group's solvable residuum in
struct.operations.RepresentativesPerfectSubgroups( struct ) called from
RepresentativesPerfectSubgroups( ShallowCopyNoSC( G ) ) called from
struct.operations.LatticeSubgroups( struct ) called from
LatticeSubgroups( G ) called from
G.operations.ConjugacyClassesMaximalSubgroups( G ) called from
What does it mean ?
Whether function MaximalSubgroups couldn't work in this case ?
