(55, 55+15, 6557005)-Net in Base 5 — Upper bound on s
There is no (55, 70, 6557006)-net in base 5, because
- 1 times m-reduction [i] would yield (55, 69, 6557006)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 1 694067 351092 958607 329442 079847 707014 991220 699225 > 569 [i]
