(142−88, 142, 2563)-Net in Base 9 — Upper bound on s

There is no (54, 142, 2564)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3186 548971 795594 879358 389855 981592 638841 520457 436848 587756 763500 246820 764086 830171 956952 175478 647718 092028 624789 333449 641280 825830 027905 > 9¹⁴² [i]
