(215−64, 215, 47272)-Net in Base 4 — Upper bound on s

There is no (151, 215, 47273)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2773 437774 163583 779714 737013 016418 974661 872691 440432 567312 108591 264457 667772 184458 577643 895052 229506 954928 158126 403221 763385 671657 > 4²¹⁵ [i]
