these are calls to random stuff, or so it seems! No wonder different
hardware gives different (pseudo?)random elements. If it were tests I'd
say they'd be marked {{{# random}}}, like
{{{
GroupAlgebra(DihedralGroup(6), QQ).random_element() # random
}}}
not sure about examples in this case though. Or else, if these random
elements are actually predictable, this could be a bug in the pseudorandom
source.
