Something similar seems to happen with `gap_console()` and `gap.console()`.

Is the x you give in these examples the same x as above? I’m worried (maybe
needlessly) about if the x you give includes a summand of kH.one(). If the
x you give does not include a summand of one, then the behavior you
described is consistent with what I think the problem is. If the x in the

I can reproduce this on 9.7.beta7.
The problem is that the parent is not understood to be the same (even
though it clearly is). A workaround is:
sage: x = kH(a) + kH(b) + kH(H.one()); x
() + (5,6,7)(12,14,18) + (1,2)(3,4)
sage: x*x
(5,7,6)(12,18,14)
Here H.one() puts the one in the right pa
I see the same issue on 9.4.beta1. It looks like maybe there is a unique
representation issue happening? That is, on your second call if irreducible
characters, it creates a new instance of the irreducible and so it doesn't
recognize them as the same. If you only compute the
