(123, 123+124, 1946)-Net in Base 4 — Upper bound on s

There is no (123, 247, 1947)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 52015 106510 369675 200116 019647 580290 542225 640285 582362 869438 206016 133126 753835 319582 102280 981596 968318 366726 770551 029779 210753 328987 568913 896130 109280 > 4²⁴⁷ [i]
