(26, 71, 80239)-Net in Base 64 — Upper bound on s

There is no (26, 71, 80240)-net in base 64, because

1 times m-reduction [i] would yield (26, 70, 80240)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2 707805 517986 409049 139446 924594 465249 510734 460423 929629 933604 114726 036084 583835 749503 936016 140686 507354 500501 713223 906049 307286 > 64⁷⁰ [i]
