4-polytope

plural 4-polytopes

1. geometryA four-dimensional polytope.

   Perhaps the most obvious next step is to investigate 4-polytopes with respect to symmetry equivalence.

   The situation for 4-polytopes is fundamentally different from that for 3-dimensional polytopes. One reason is that there is no similar reduction of 4-polytope theory to a combinatorial (graph) problem.

   For d = 4, Hamiltonian cycles in the regular 4-polytopes are known to exist. However, it seems that so far no decision about the existence or non-existence of 1-Hamiltonian surfaces in the 2-skeleton of any of the three sporadic regular 4-polytopes can be made, compare [120].
