(245−146, 245, 490)-Net in Base 3 — Upper bound on s

There is no (99, 245, 491)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 858 879627 378598 773337 958540 818897 264389 875503 979008 688920 412354 166067 819016 717682 278229 877499 780490 248570 600833 040391 > 3²⁴⁵ [i]
