{{{
SymmetricGroup(6).minimal_generating_set()
RuntimeError: Gap produced error output
Error, `MinimalGeneratingSet' currently assumes that the group must be
solvable.
In general, try `SmallGeneratingSet' instead, which returns a generating
set that is small but not of guarateed smallest cardinality
executing MinimalGeneratingSet($sage1);
}}}
Gap's error is okay, but the thing at the end is confusing and may send
some readers astray. Anyway, we should probably catch this error and say
something like input or value error in such cases.
