(142, 142+96, 2128)-Net in Base 3 — Upper bound on s

There is no (142, 238, 2129)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 366312 921228 463933 010113 832056 401126 624106 546574 824448 458470 281776 793400 950960 718882 654380 416220 489836 021557 569985 > 3²³⁸ [i]
