(91−29, 91, 47063)-Net in Base 5 — Upper bound on s
There is no (62, 91, 47064)-net in base 5, because
- 1 times m-reduction [i] would yield (62, 90, 47064)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 807 917226 442637 750061 481028 177381 667707 781693 256815 634695 352705 > 590 [i]
