(226−140, 226, 731)-Net in Base 4 — Upper bound on s

There is no (86, 226, 732)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12231 406944 333540 774954 252323 804535 730587 321117 033179 026691 945787 171000 516313 400458 227501 691189 176311 532945 901387 996319 346580 773710 867614 > 4²²⁶ [i]
