(125−53, 125, 388966)-Net in Base 16 — Upper bound on s

There is no (72, 125, 388967)-net in base 16, because

1 times m-reduction [i] would yield (72, 124, 388967)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 204596 678393 374484 686459 420150 143551 802773 128303 114770 244290 925818 078744 852619 450797 585556 012828 157546 304123 059593 227098 173291 980652 179860 861086 672756 > 16¹²⁴ [i]
