(148, 183, 6674311)-Net in Base 4 — Upper bound on s
There is no (148, 183, 6674312)-net in base 4, because
- 1 times m-reduction [i] would yield (148, 182, 6674312)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 37 576688 901051 144864 052910 943864 115359 026387 686391 692229 858415 473309 876281 914929 711523 271864 004067 491079 128680 > 4182 [i]
