I see. But should I do anything about it at this point?
> this ceritainly looks better, but again, I don't like the counter-
intuitive parameters of `is_cayley()` and weird sort of output (a pair)
that you currently have. In particular the latter.
I have modelled both input and output of `is_cayley` after methods such as
`is_chordal` and `is_circulant`. I guess we could be even more specific
and have the function return only the group or only the generators if
requested - or maybe `cayley_graph_group` could do that, and `is_cayley`
would then simply call `cayley_graph_group` without requesting either.
