(131−82, 131, 2233)-Net in Base 9 — Upper bound on s

There is no (49, 131, 2234)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 103078 374859 457997 254417 974961 173218 489086 682944 299795 842862 773497 538337 880197 282605 580782 511424 263743 563651 939729 455607 877969 > 9¹³¹ [i]
