Hi Nicolas,
If you want your patch to be reviewed please check "needs review"...
For your information your patch breaks posets which use permutations
starting from 0:
{{{
sage: P = Posets.SymmetricGroupBruhatIntervalPoset([0,1,2,3],
[2,3,0,1])
Exception raised:
...
ValueError: [0, 1, 2, 3] is not a Standard permutations
}}}
