(84, 84+134, 728)-Net in Base 4 — Upper bound on s

There is no (84, 218, 729)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 191980 093467 935223 844285 224271 751128 544563 564116 730150 100649 426523 990776 210066 493149 852065 136173 298904 037568 686897 567357 319035 789560 > 4²¹⁸ [i]
