(140, 140+88, 2516)-Net in Base 3 — Upper bound on s

There is no (140, 228, 2517)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 6 091576 198396 651505 387197 439399 792795 242059 692457 765449 476366 476750 673189 850876 513376 802684 782994 015568 807985 > 3²²⁸ [i]
