(245−130, 245, 1499)-Net in Base 4 — Upper bound on s

There is no (115, 245, 1500)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3327 894828 062829 842860 588291 913230 955181 907460 033522 958205 778769 155166 321441 543348 504145 396815 793422 556894 071300 826288 277123 604022 769726 442584 380531 > 4²⁴⁵ [i]
