(169, 169+72, 51029)-Net in Base 4 — Upper bound on s

There is no (169, 241, 51030)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 490622 829811 564929 609254 041094 027969 510226 953546 783032 601645 744502 571413 380149 325001 639260 599202 477175 824274 541156 584273 603064 815309 336471 099322 > 4²⁴¹ [i]
