(59, 59+19, 990296)-Net in Base 5 — Upper bound on s
There is no (59, 78, 990297)-net in base 5, because
- 1 times m-reduction [i] would yield (59, 77, 990297)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 661745 090561 362897 692071 954759 964452 928658 341268 853445 > 577 [i]
