(99, 124, 2614288)-Net in Base 4 — Upper bound on s
There is no (99, 124, 2614289)-net in base 4, because
- 1 times m-reduction [i] would yield (99, 123, 2614289)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 113 078536 002735 496349 763847 768756 662334 472637 393864 267628 994320 561645 296220 > 4123 [i]
