Generated by Warren D. Smith & Fred Lunnon, December 2011. "Heron" tetrahedra = all sides, face-areas, and volume = integers. "Primitive" = gcd(sidelengths)=1. [We proved the theorem that volume is always divisible by 168 but this is not true for any divisor greater than 168.] [A much larger list of Heron tetrahedra, up to diameter 70000, was constructed by Sascha Kurz but a bug in his program caused a small fraction of omissions -- 4%?.] Census: A=[diameter] B=[#primtets with diam<=A] C=[exponent in power law estimated from this & preceding count] A B C
