(160, 160+74, 31332)-Net in Base 4 — Upper bound on s

There is no (160, 234, 31333)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 762 720991 168482 900969 332067 477710 306978 801339 309642 719336 651039 700208 342163 386728 002562 590684 423708 104543 274380 482084 093851 436564 234734 822060 > 4²³⁴ [i]
