(256−116, 256, 3352)-Net in Base 4 — Upper bound on s

There is no (140, 256, 3353)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13549 411019 696508 341736 222445 739667 963651 439911 417434 768218 897994 197574 259048 165217 342135 012467 640052 054440 575933 695869 974113 047600 176434 677935 101664 098560 > 4²⁵⁶ [i]
