(142−112, 142, 679)-Net in Base 9 — Upper bound on s

There is no (30, 142, 680)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3381 046520 837767 330256 444954 975721 572773 848206 675608 234045 998420 120376 332565 633880 110168 944205 129233 881389 045226 606363 494802 033362 459137 > 9¹⁴² [i]
