“…Following Petrov and Todorov [8] we divide the tesseract T i optimally with respect to the measure of degeneracy. Let T be the partition technique [8] subdividing T i uniformly into 24 tesseract corners C i j , i = 1, 2, ..., 10 and j = 1, 2, ..., 24. Despite all 24 elements C i j , j = 1, 2, ..., 24 are from the same class we distinguish two kind of pentatopes belonging to T T i : (i) tesseract corners that satisfy a i+32 ∈ V (C i j ); (ii) elements that a i+32 ∈ V (C i j ).…”
