Gilbertâ€“VarÅ¡amov bound [i]

(141, 141+114, 3586)-Net in Base 4 — Upper bound on s

There is no (141, 255, 3587)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3377 039077 704014 617294 561278 505291 245491 364362 302933 597652 933268 782766 113349 516150 547676 229493 594740 605693 859062 299405 020219 557687 506241 231068 076142 217600 > 4²⁵⁵ [i]
