(93, 118, 118637)-Net in Base 3 — Upper bound on s
There is no (93, 118, 118638)-net in base 3, because
- 1 times m-reduction [i] would yield (93, 117, 118638)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 66 560091 783328 830817 655914 733802 114854 155723 663584 126169 > 3117 [i]
