Comment (by ncohen):
> 1) GQs don't necessary admit parameters; e.g.
I implemented the definition from Wikipedia:
https://en.wikipedia.org/wiki/Generalized_quadrangle
Is it wrong?
> 2) the incidence graph is bipartite, and thus must have even girth
(equal to 8, to get a GQ).
Soooooooooo you want me to change something in my code/doc, arguing that
it would make absolutely no difference because both are correct? `:-P`
