I have a pairwise dataset with 634 nodes and 18624 edges.
I want to fill its empty triangles with probability p.
We have a function `flag_complex` that does exactly this, but it's slow: after runni…

So far the face iterator for polyhedra assumes the diamond property of the lattice only. The special case of simple/simplicial polytopes is not exploited. In this case all intervals not containing z…
