(158, 158+62, 77527)-Net in Base 4 — Upper bound on s

There is no (158, 220, 77528)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 840214 339037 724170 273655 443010 739769 770316 849639 949122 209249 717516 853664 640751 211013 714565 843719 872415 166218 884597 551874 574927 716440 > 4²²⁰ [i]
