(20, 20+58, 42740)-Net in Base 128 — Upper bound on s

There is no (20, 78, 42741)-net in base 128, because

the generalized Rao bound for nets shows that 128^mÂ â‰¥ 230 386221 154350 489096 964518 266039 760641 104332 893572 942435 317389 159243 360254 798731 531793 530303 508273 241722 475705 528273 636160 415111 753569 914828 569125 426957 521999 919456 > 128⁷⁸ [i]
