(122, 122+124, 875)-Net in Base 3 — Upper bound on s

There is no (122, 246, 876)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2406 852605 589147 881303 417608 656865 026766 835950 795821 569605 998222 393660 396799 483219 455475 825371 672771 615394 390118 712009 > 3²⁴⁶ [i]
