(64, 64+27, 97797)-Net in Base 5 — Upper bound on s
There is no (64, 91, 97798)-net in base 5, because
- 1 times m-reduction [i] would yield (64, 90, 97798)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 807 835956 009845 183354 103313 267451 150421 562266 159606 890068 622745 > 590 [i]
