(34, 34+27, 668684)-Net in Base 25 — Upper bound on s
There is no (34, 61, 668685)-net in base 25, because
- 1 times m-reduction [i] would yield (34, 60, 668685)-net in base 25, but
- the generalized Rao bound for nets shows that 25m ≥ 752318 277764 823918 168030 531690 209507 981112 983236 019046 580292 763489 725649 318651 977305 > 2560 [i]
