P.S. : This patch "does not really" depend on #14589, but here is what
happens when calling "is_strongly_regular" on a big graph. With the patch
:
{{{
sage: g
Affine Polar Graph VO^+(10,2): Graph on 1024 vertices
sage: %time g.is_strongly_regular(parameters = True)
CPU times: user 3.30 s, sys: 0.00 s, total: 3.30 s
Wall time: 3.31 s
(1024, 527, 270, 272)
}}}
Without the patch
{{{
sage: %time g.is_strongly_regular(parameters = True)
CPU times: user 316.33 s, sys: 0.08 s, total: 316.41 s
Wall time: 317.20 s
(1024, 527, 270, 272)
}}}
Annnnnd the doctests that this patch adds are a bit faster as a result
`:-P`
