(107−31, 107, 38465)-Net in Base 4 — Upper bound on s
There is no (76, 107, 38466)-net in base 4, because
- 1 times m-reduction [i] would yield (76, 106, 38466)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 6584 250081 985757 427736 760524 431145 907933 680567 652607 935949 512992 > 4106 [i]
