(215−102, 215, 2242)-Net in Base 4 — Upper bound on s

There is no (113, 215, 2243)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2772 678677 541227 215811 095010 449247 312686 612987 026987 214558 946827 879583 761571 813150 539538 563749 003282 877231 581473 635334 434761 552880 > 4²¹⁵ [i]
