(21, 50, 36144)-Net in Base 32 — Upper bound on s

There is no (21, 50, 36145)-net in base 32, because

1 times m-reduction [i] would yield (21, 49, 36145)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 56 558745 545923 804365 026104 724026 934242 135281 167429 976061 874111 318149 468424 > 32⁴⁹ [i]
