(180, 250, 92562)-Net in Base 4 — Upper bound on s

There is no (180, 250, 92563)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 273612 435368 347347 131483 065426 219904 802145 210713 391620 667951 510722 935795 003792 833942 564933 506778 217947 943864 548990 303934 457179 285480 576865 447231 980560 > 4²⁵⁰ [i]
