Comment (by aschilling):
Hi Nathann,
To be honest, I cannot even reproduce the bug that you reported
{{{
sage: d = DiGraph({2:[1],3:[1]})
sage: sage: p1 = Poset(d)
sage: sage: p2 = p1.relabel({1:1,2:3,3:2})
/Applications/sage/src/bin/sage-ipython:1:
********************************************************************************
Relabelling posets is known to break equality between posets (P == Q)
This issue is being tracked at
http://trac.sagemath.org/sage_trac/ticket/14019.
********************************************************************************
sage: sage: p1.hasse_diagram() == p2.hasse_diagram()
True
sage: p1 == p2
True
}}}
Is it possible that this was already fixed with #17059? I am running
sage-6.4.beta4.
Anne
