(21, 21+35, 17138)-Net in Base 32 — Upper bound on s

There is no (21, 56, 17139)-net in base 32, because

1 times m-reduction [i] would yield (21, 55, 17139)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 60745 553627 361181 073235 743041 552637 427609 634043 154065 870746 427429 345241 340278 616042 > 32⁵⁵ [i]
