(239−134, 239, 585)-Net in Base 3 — Upper bound on s

There is no (105, 239, 586)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 158699 285443 308266 402297 066909 777451 298009 045524 797824 311682 923495 398321 215877 567524 845783 026625 859681 174956 281393 > 3²³⁹ [i]
