(131−90, 131, 1293)-Net in Base 9 — Upper bound on s

There is no (41, 131, 1294)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 102006 439613 676730 625958 573025 800243 569586 719614 302566 852540 346039 430319 294946 405595 826104 047616 025262 550550 981626 288052 100913 > 9¹³¹ [i]
