(77, 102, 1009939)-Net in Base 5 — Upper bound on s

There is no (77, 102, 1009940)-net in base 5, because

1 times m-reduction [i] would yield (77, 101, 1009940)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 39443 339138 101135 376953 469958 274502 511790 706448 439298 462203 126517 185281 > 5¹⁰¹ [i]
