(71, 217, 517)-Net in Base 4 — Upper bound on s

There is no (71, 217, 518)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 49310 236835 294339 347243 861131 125471 143814 148734 786722 092559 452671 926531 000401 901431 942869 765234 482189 773606 559568 963082 092979 966400 > 4²¹⁷ [i]
