(181−58, 181, 22244)-Net in Base 4 — Upper bound on s

There is no (123, 181, 22245)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 9 399490 606170 786581 358297 050772 609551 843814 330162 867494 189793 609470 616752 183864 209675 210658 718103 429492 681936 > 4¹⁸¹ [i]
