Dear Gap Forum,

What happened?

GAP4.3 contains only methods to compute the socle of a primitive permutation
group. (The next release will contain a more general method.)

You can use `NormalSubgroups' to get a list of all normal subgroups and filter
out the minimal ones to obtain the socle.

Best wishes,
