(131, 131+106, 3336)-Net in Base 4 — Upper bound on s
There is no (131, 237, 3337)-net in base 4, because
- the generalized Rao bound for nets shows that 4m ≥ 49222 974303 822433 816303 807539 964070 744166 650341 387617 834809 084326 362775 389189 108339 723346 158976 164903 643129 248060 087182 981317 053479 851709 916160 > 4237 [i]
