(18, 18+49, 4344)-Net in Base 32 — Upper bound on s

There is no (18, 67, 4345)-net in base 32, because

1 times m-reduction [i] would yield (18, 66, 4345)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2193 381377 883453 537644 229532 105402 371075 352782 361274 119160 633664 395031 173415 853092 755619 222791 955607 > 32⁶⁶ [i]
