(237−160, 237, 556)-Net in Base 4 — Upper bound on s

There is no (77, 237, 557)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 55067 196323 833386 727768 757739 201415 415528 644510 734655 751742 675422 077170 632245 646101 642810 137413 084920 976600 051238 013694 386740 207057 210413 379760 > 4²³⁷ [i]
