(247−154, 247, 428)-Net in Base 3 — Upper bound on s

There is no (93, 247, 429)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 8042 242793 223431 201503 858481 548847 123865 869488 971256 833442 664902 286753 153707 266856 431913 455580 474563 271293 425768 403147 > 3²⁴⁷ [i]
