(20, 20+25, 352106)-Net in Base 64 — Upper bound on s
There is no (20, 45, 352107)-net in base 64, because
- 1 times m-reduction [i] would yield (20, 44, 352107)-net in base 64, but
- the generalized Rao bound for nets shows that 64m ≥ 29 643519 286554 975533 006156 973134 837754 543077 988824 838026 072614 807712 910824 132680 > 6444 [i]
