(40, 138, 1133)-Net in Base 9 — Upper bound on s

There is no (40, 138, 1134)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 497920 513474 825348 255485 387729 715058 010635 887051 735040 870699 159655 527216 298823 110578 832139 068651 588051 700614 094239 699936 054906 584689 > 9¹³⁸ [i]
