(238−133, 238, 220)-Net in Base 2 — Upper bound on s
There is no (105, 238, 221)-net in base 2, because
- 1 times m-reduction [i] would yield (105, 237, 221)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 268918 575332 246348 409561 851474 920729 198811 928853 782876 660995 402897 091258 > 2237 [i]
