(180, 248, 111107)-Net in Base 4 — Upper bound on s

There is no (180, 248, 111108)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 204643 263155 935087 411472 721229 566001 479962 677728 078100 885914 437627 891085 558585 577890 589291 388536 472537 246201 019086 842887 078683 861222 943653 168131 864912 > 4²⁴⁸ [i]
