(21, 21+56, 55452)-Net in Base 128 — Upper bound on s

There is no (21, 77, 55453)-net in base 128, because

the generalized Rao bound for nets shows that 128^mÂ â‰¥ 1 800001 646440 631282 485220 278709 269329 588182 806143 621163 908892 953147 641183 243768 373723 970541 060089 182891 314350 980600 918098 497731 964061 272327 206068 178520 059499 079049 > 128⁷⁷ [i]
