(93, 93+142, 836)-Net in Base 4 — Upper bound on s

There is no (93, 235, 837)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3158 008246 240843 965087 955892 014864 590651 224718 214832 654485 100958 021198 864720 472236 948623 238241 023126 948006 344745 324853 099342 074150 797734 210240 > 4²³⁵ [i]
