#4105: multiplication of permutations in distinct subgroups sometimes doesn't
work

Comment (by wdj):
I'm not sure I should be the owner of this. I guess the _mul_ method
should be changed to coerce the PermutationGroup elements into a common
parent (like SymmetricGroup(n), where n =
largest_moved_point=LargestMovedPoint). Now the module for
permutation_group_element is in Cython and the method _mul_ seems to be
renamed as cdef MonoidElement _mul_c_impl ?
I don't know how to make the changes though, sorry.
