(121−95, 121, 1427)-Net in Base 16 — Upper bound on s

There is no (26, 121, 1428)-net in base 16, because

1 times m-reduction [i] would yield (26, 120, 1428)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 3 194468 602902 558686 381922 892030 502433 371180 963740 646224 885657 367171 325949 087493 391493 954005 289971 881891 542105 618194 904142 346354 670570 201714 399216 > 16¹²⁰ [i]
