(222−94, 222, 4234)-Net in Base 4 — Upper bound on s

There is no (128, 222, 4235)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45 606325 915153 758012 154519 385766 684944 220659 064606 616028 771366 727695 859481 021054 511064 155974 480793 477227 328945 286772 565242 774734 386944 > 4²²² [i]
