(54, 140, 2672)-Net in Base 9 — Upper bound on s

There is no (54, 140, 2673)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 39 402204 864192 794715 459676 639547 963718 701612 098550 358411 856151 703972 535507 786429 384733 306734 236465 657910 358934 752938 314547 888475 007385 > 9¹⁴⁰ [i]
