(91−67, 91, 1669)-Net in Base 16 — Upper bound on s

There is no (24, 91, 1670)-net in base 16, because

1 times m-reduction [i] would yield (24, 90, 1670)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 2 381765 134534 386957 346215 112791 590594 202455 683618 640878 608672 298544 071485 629857 145091 216460 587023 135691 310276 > 16⁹⁰ [i]
