(238−140, 238, 497)-Net in Base 3 — Upper bound on s

There is no (98, 238, 498)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 390604 370008 853196 514762 509399 643402 331525 132250 045018 892026 726114 315570 948649 135040 755969 828243 183548 086293 617501 > 3²³⁸ [i]
