The facade Posets (i.e. the default ones) are parents, and it seems that

Could anybody confirm that ? Also, would anybody know how to make it

Interval fields apparently hide this (intervals are equal if they have

this notion of equality isn't transitive. The bug is that CIF elements are

With that in mind, it seems that DiGraph is fine as those points are

DiGraphs consider that two points u,v with u==v are the same points.
