(117, 117+134, 1493)-Net in Base 4 — Upper bound on s

There is no (117, 251, 1494)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 519511 573512 713640 494651 617439 902584 432730 488937 561431 625565 516488 508584 261966 587997 791801 999070 701112 449220 795526 113870 960287 811542 645216 069048 304530 > 4²⁵¹ [i]
