(36, 57, 73815)-Net in Base 8 — Upper bound on s

There is no (36, 57, 73816)-net in base 8, because

1 times m-reduction [i] would yield (36, 56, 73816)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 374 171948 977115 817647 256867 995371 240190 631742 738922 > 8⁵⁶ [i]
