(237−138, 237, 512)-Net in Base 3 — Upper bound on s

There is no (99, 237, 513)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 134164 185485 035483 322362 627519 029750 304248 644009 542258 177208 310316 603665 722920 173003 936976 428838 835357 418478 971891 > 3²³⁷ [i]
