(96, 96+33, 148545)-Net in Base 4 — Upper bound on s
There is no (96, 129, 148546)-net in base 4, because
- 1 times m-reduction [i] would yield (96, 128, 148546)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 115796 689532 779832 481013 608012 995464 947891 734192 640953 581688 808594 234409 278364 > 4128 [i]
