(40, 140, 1113)-Net in Base 9 — Upper bound on s

There is no (40, 140, 1114)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 40 033584 956322 249680 416516 482923 980169 252948 376302 767831 410266 291519 002403 746909 068988 604979 579404 109101 408361 779199 666385 292436 560481 > 9¹⁴⁰ [i]
