(93, 93+70, 293)-Net in Base 2 — Upper bound on s
There is no (93, 163, 294)-net in base 2, because
- extracting embedded orthogonal array [i] would yield OA(2163, 294, S2, 70), but
- 5 times code embedding in larger space [i] would yield OA(2168, 299, S2, 70), but
- adding a parity check bit [i] would yield OA(2169, 300, S2, 71), but
