Talk:Trirectangular tetrahedron

Fundamental domains
Interestingly only the bifurcating graph of the $${\tilde{B}}_3$$ Affine Coxeter group has a Trirectangular tetrahedron fundamental domain (as shown in the middle tetrahedron in this graphic below). Tom Ruen (talk) 03:40, 5 January 2012 (UTC)

Perfect Body
The article states "The area of the base (a,b,c) is always (Gua) an irrational number." A link or specific citation proving this claim is needed. Zubaroo (talk) 20:28, 2 February 2023 (UTC)

A link to https://en.wikipedia.org/wiki/Heronian_tetrahedron would provide a definition for how "perfect" is (mathematically) defined in this context. Also "perfect body" draws many unrelated (human physiology) search hits. For consistency, I suggest revising it to one of the three terms on that page. — Preceding unsigned comment added by Zubaroo (talk • contribs) 02:02, 4 February 2023 (UTC)
