(149, 149+90, 2970)-Net in Base 3 — Upper bound on s

There is no (149, 239, 2971)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 091303 629252 190239 778824 299064 807375 102179 004121 631928 959031 656547 534739 141050 178794 117000 511115 104191 241833 024479 > 3²³⁹ [i]
