(142, 248, 1707)-Net in Base 3 — Upper bound on s

There is no (142, 248, 1708)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21575 964777 759898 460044 542304 122002 378574 503677 104242 891478 139348 654013 930883 646981 147133 105454 172995 109856 135839 100217 > 3²⁴⁸ [i]
