(248−90, 248, 3710)-Net in Base 3 — Upper bound on s

There is no (158, 248, 3711)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21254 425447 948363 205108 908898 517557 888437 822320 672307 632867 649717 160081 421724 372957 822307 180608 064547 134897 302244 706471 > 3²⁴⁸ [i]
