[sage-support] Bug in scalar products of characters coming from restrictions

2020-08-14 Thread 'Peter Mueller' via sage-support
In the code below g1 and g2 are the same group, where g2 is produced as a subgroup of g1, and c is the principal character of g1. Still, when it comes to scalar products, somehow g1 is not considered as a subgroup of itself: sage: g1 = SymmetricGroup(2) : g2 = g1.conjugacy_classes_subgroups

[sage-support] Weird bug in libgap?

The following code yields a Traceback for no (to me) obvious reason. The same happens on sagecell too. It seems to be a minimal case. For instance removing the line "P = ..." or having less deeply nested loops does not display this problem: for A in PrimitiveGroups(3): for G in A.normal_sub
