Finiteness conjecture for Forman–Ricci-positive 5-polytopes

Let PP be a polytope, and call it Forman–Ricci-positive when its Forman–Ricci curvature satisfies κF(e)>0\kappa_F(e)>0 for every edge ee. Finiteness conjecture for Forman–Ricci-positive 5-polytopes. There are finitely many Forman–Ricci-positive 55-polytopes.

The statement is a restatement of the conjecture posed after the preceding finiteness theorem for simplicial 55-polytopes; it is intended to extend finiteness to all 55-dimensional polytopes. The source gives no resolution status.
