Gilbertâ€“VarÅ¡amov bound [i]

(243−114, 243, 1138)-Net in Base 3 — Upper bound on s

There is no (129, 243, 1139)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 88 877722 131537 720353 616247 659141 343200 461612 538117 520604 427261 541922 450954 993113 832230 626012 950149 142176 636195 938231 > 3²⁴³ [i]
