(195−86, 195, 2989)-Net in Base 4 — Upper bound on s

There is no (109, 195, 2990)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2554 737778 560513 772892 195235 602120 411853 905022 464404 716477 005611 803557 625094 707472 326240 121967 223459 646243 008793 761610 > 4¹⁹⁵ [i]
