(70−37, 70, 143377)-Net in Base 32 — Upper bound on s
There is no (33, 70, 143378)-net in base 32, because
- 1 times m-reduction [i] would yield (33, 69, 143378)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 71 672056 981533 576291 191435 760307 191068 465322 620514 036687 363903 244202 830738 477577 548065 589545 935108 407744 > 3269 [i]
