(199−130, 199, 530)-Net in Base 4 — Upper bound on s

There is no (69, 199, 531)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 721987 365541 959483 902743 709965 080731 873864 836373 239554 524535 661955 868601 800033 538545 334725 403977 991830 865316 881662 478960 > 4¹⁹⁹ [i]
