(139−94, 139, 1495)-Net in Base 9 — Upper bound on s

There is no (45, 139, 1496)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 4 389803 382021 387774 694452 282224 469757 967776 703828 171373 138941 972729 606897 065382 851939 540907 898244 379228 265826 190819 109801 040352 628801 > 9¹³⁹ [i]
