(143−94, 143, 1809)-Net in Base 9 — Upper bound on s

There is no (49, 143, 1810)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 29177 745565 259291 252807 488980 039232 068793 136342 519831 110525 031454 044177 144226 126321 413301 552061 204645 937630 419876 763202 444399 877523 238705 > 9¹⁴³ [i]
