Inscribing a k-simplex on the vertices of a k-cube is only possible when k is congruent to 3 mod 4 (excluding the trivial cases of k=0,1).
Table of n, a(n) for n=0..6.
Andrew Weimholt, Further comments
a(0) = 2 because two regular tetrahedra can be inscribed on the vertices of a cube.
See A124505 for another version.
