(17, 17+23, 197420)-Net in Base 64 — Upper bound on s
There is no (17, 40, 197421)-net in base 64, because
- 1 times m-reduction [i] would yield (17, 39, 197421)-net in base 64, but
- the generalized Rao bound for nets shows that 64m ≥ 27608 471383 148612 797821 919349 584706 632879 457567 598604 381218 053106 163204 > 6439 [i]
