(182−122, 182, 442)-Net in Base 4 — Upper bound on s

There is no (60, 182, 443)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 38 007174 015228 413477 454113 599813 075207 723260 134525 496548 843377 532866 688205 784696 270194 880448 689452 501028 651840 > 4¹⁸² [i]
