| Sep 30, 2017 at 14:52 | comment | added | Nate Eldredge | Is there really not an OEIS entry that just lists integer-edge length tetrahedra, without restrictions on area or volume? If not, then maybe someone should create it... | |

| Sep 29, 2017 at 5:26 | comment | added | Noam D. Elkies | According to the A272388 text, Heronian = "edge lengths, face areas and volume are all integers". But here only integral edge lengths are required, right? | |
