(212−132, 212, 674)-Net in Base 4 — Upper bound on s

There is no (80, 212, 675)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45 168466 147441 090238 053075 218637 037846 189797 112472 217013 143535 786388 825821 652960 030787 791512 284775 487357 947664 102264 002079 070570 > 4²¹² [i]
