(115, 115+122, 1665)-Net in Base 4 — Upper bound on s

There is no (115, 237, 1666)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50236 005713 405331 507310 972971 273037 727962 566868 454660 107438 981916 523371 397992 985948 352408 114637 213888 792513 452258 436486 471124 005810 339485 322080 > 4²³⁷ [i]
