(121, 245, 1859)-Net in Base 4 — Upper bound on s

There is no (121, 245, 1860)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3287 445840 775257 656861 363829 066307 705538 766970 947116 689580 286993 194453 359956 621938 386489 530108 044768 825792 818070 568580 773393 386163 613091 198130 146800 > 4²⁴⁵ [i]
