(239−96, 239, 2178)-Net in Base 3 — Upper bound on s

There is no (143, 239, 2179)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 090200 576604 110722 064248 196857 187239 562965 321321 468199 302982 716215 184480 778539 816179 332069 725765 609080 873165 986465 > 3²³⁹ [i]
