(131−86, 131, 1677)-Net in Base 9 — Upper bound on s

There is no (45, 131, 1678)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 101793 730528 894894 514942 047850 852699 639626 467882 223898 327745 104527 709969 195882 185522 568886 752576 201374 071324 382511 682627 745425 > 9¹³¹ [i]
