(91, 237, 782)-Net in Base 4 — Upper bound on s

There is no (91, 237, 783)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 52195 282236 092852 629406 378086 002410 832188 004546 509551 566477 957922 646447 805703 680489 747505 570566 747156 468945 734384 442439 318713 286008 256212 001000 > 4²³⁷ [i]
