(222−64, 222, 64028)-Net in Base 4 — Upper bound on s

There is no (158, 222, 64029)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45 440260 252076 668269 084115 237287 320773 918942 854748 226468 434515 824366 025989 971683 388939 372902 985104 910009 817685 656013 804665 086549 274320 > 4²²² [i]
