group-using-computer-software this math.SX question].
{{{
G = CyclicPermutationGroup(4)
H = CyclicPermutationGroup(2)
D=G.direct_product(H)
D.AutomorphismGroup()
<boom>
}}}
Okay, that's because you receive a tuple back. But
{{{
d = D[0]
d.AutomorphismGroup()
<boom for different and more annoying reason>
}}}
Also, there is no `gap()` method for such groups, only a `_gap_()` method,
which most people will not know about.
