(228−54, 228, 441902)-Net in Base 4 — Upper bound on s

There is no (174, 228, 441903)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 186081 192816 887124 976317 495263 393456 799805 352270 968124 453522 175459 141976 665476 226021 552779 967888 166016 062767 759048 656792 797708 340425 369216 > 4²²⁸ [i]
