(240−68, 240, 15755)-Net in Base 3 — Upper bound on s

There is no (172, 240, 15756)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 231114 510642 599442 302080 986756 777992 661193 402476 351142 563012 866995 566052 584190 292744 022609 368401 429450 496854 149225 > 3²⁴⁰ [i]
