(240−82, 240, 4969)-Net in Base 3 — Upper bound on s

There is no (158, 240, 4970)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 254175 752138 545871 958858 031819 862865 653458 722940 104060 982677 488399 648173 135177 923480 143584 296334 575983 117550 447045 > 3²⁴⁰ [i]
