(99−51, 99, 757)-Net in Base 4 — Upper bound on s

There is no (48, 99, 758)-net in base 4, because

1 times m-reduction [i] would yield (48, 98, 758)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 103206 736870 288777 655680 298806 972528 446388 771397 839481 500804 > 4⁹⁸ [i]
