(77, 77+108, 763)-Net in Base 4 — Upper bound on s

There is no (77, 185, 764)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2451 920337 552737 922051 826798 820204 891136 396062 467146 288830 248667 008900 353326 699420 971350 607397 821211 696024 414494 > 4¹⁸⁵ [i]
