(56, 143, 2963)-Net in Base 9 — Upper bound on s

There is no (56, 143, 2964)-net in base 9, because

1 times m-reduction [i] would yield (56, 142, 2964)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3217 372612 683983 878609 581535 195960 452715 103833 172774 882210 448127 422436 698696 607639 873322 990592 938763 226158 571522 714661 619862 212952 053345 > 9¹⁴² [i]
