A pseudo-edge graph of a convex polyhedronKis a 3-connected embedded graph inKwhose vertices coincide with those ofK, whose edges are distance minimizing geodesics, and whose faces are convex. We construct a convex polyhedronKin Euclidean 3-space with a pseudo-edge graph with respect to whichKis not unfoldable. The proof is based on a result of Pogorelov on convex caps with prescribed curvature, and an unfoldability obstruction for almost flat convex caps due to Tarasov. Our example, which has 340 vertices, significantly simplifies an earlier construction by Tarasov, and confirms that Dürer’s conjecture does not hold for pseudo-edge unfoldings.
