(231−108, 231, 2585)-Net in Base 4 — Upper bound on s

There is no (123, 231, 2586)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 043534 025809 589000 849300 370415 931431 635065 549874 883626 238734 766931 075806 286999 645770 642277 324929 052418 306670 854168 306383 255912 202029 310400 > 4²³¹ [i]
