(139, 257, 3141)-Net in Base 4 — Upper bound on s

There is no (139, 257, 3142)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 54309 346657 190878 574770 535456 312393 157902 641786 367834 418995 968436 111953 242426 062143 311985 589807 771324 329214 173091 249406 727110 555638 621468 905598 699581 826512 > 4²⁵⁷ [i]
