(234−140, 234, 866)-Net in Base 4 — Upper bound on s

There is no (94, 234, 867)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 795 239132 610274 539438 693817 034020 607024 996745 575056 819356 942341 638800 958463 686632 720689 695647 763471 529651 452852 057605 024516 497024 855333 876824 > 4²³⁴ [i]
