(102, 102+31, 50731)-Net in Base 3 — Upper bound on s
There is no (102, 133, 50732)-net in base 3, because
- 1 times m-reduction [i] would yield (102, 132, 50732)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 955 083878 063421 836131 005620 716393 066942 054857 031124 407979 623441 > 3132 [i]
