Gilbertâ€“VarÅ¡amov bound [i]

(177−66, 177, 7411)-Net in Base 4 — Upper bound on s

There is no (111, 177, 7412)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 36831 871006 437578 832802 219118 283278 549881 786824 589861 602236 708361 854044 790599 533975 355563 872101 723651 688905 > 4¹⁷⁷ [i]
