(111, 219, 1888)-Net in Base 4 — Upper bound on s

There is no (111, 219, 1889)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 722970 355998 014217 494730 976065 900139 568986 537377 434329 588238 302566 102176 136321 046585 268287 151044 278597 513045 286967 885667 438419 199904 > 4²¹⁹ [i]
