(107, 257, 1047)-Net in Base 4 — Upper bound on s

There is no (107, 257, 1048)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 56360 187176 330909 334452 058199 912374 072997 720687 843199 091856 265503 043632 268294 921153 314312 681456 219533 938381 095686 108365 226924 732762 947022 192407 028700 127968 > 4²⁵⁷ [i]
