(This challenge exists to extend sequence A276272 in the On-Line Encyclopedia of Integer Sequences, and perhaps create a new OEIS sequence1.) This is a code-challenge, which will have you write code to compute as many terms of this sequence as possible. --- Background A polytet is a kind of polyform which is constructed by gluing regular tetrahedra together face-to-face in such a way that none of the interiors of the tetrahedra overlap. These are counted up to rotation in 3-space but not refl...
