Web@hagenvoneitzen there are 6 edges and hence 6 division points. This give 15 tetrahedra but 3 of them are degenerate. The number I don't understand is 6554147. This is smaller than 12 (N-1)^4, a trivial lower bound I can establish. – Feb 17, 2013 at 16:31 I don't see the 3 degenerate ones in the $N=2$ case.
