(44, 79, 1864505)-Net in Base 32 — Upper bound on s

There is no (44, 79, 1864506)-net in base 32, because

1 times m-reduction [i] would yield (44, 78, 1864506)-net in base 32, but
- the generalized Rao bound for nets shows that 32^mÂ â‰¥ 2521 729383 970096 522042 453825 012318 506071 122969 348803 050444 518111 203397 729900 013203 355284 915084 377283 106620 487116 543135 > 32⁷⁸ [i]
