Gilbertâ€“VarÅ¡amov bound [i]

(231−98, 231, 4349)-Net in Base 4 — Upper bound on s

There is no (133, 231, 4350)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11 926960 719767 026489 601110 331077 757622 374426 260423 208752 678247 363624 179523 574089 534383 611620 871276 985780 985522 008619 518759 467250 542109 469563 > 4²³¹ [i]
