(82, 82+150, 289)-Net over F3 — Upper bound on s (digital)
There is no digital (82, 232, 290)-net over F3, because
- extracting embedded orthogonal array [i] would yield linear OA(3232, 290, F3, 150) (dual of [290, 58, 151]-code), but
- residual code [i] would yield OA(382, 139, S3, 50), but
- the linear programming bound shows that M ≥ 1587 399042 866016 986303 890803 537138 245492 206166 258555 218457 073292 762725 146456 195326 962155 694534 950498 243860 513481 979544 181045 609868 510228 655317 898137 944968 273836 801278 213469 / 1 121662 775947 035202 501592 579753 339451 946215 941077 958998 362092 006927 786507 022495 318993 197038 312138 033878 088343 981406 194796 277022 130176 > 382 [i]
- residual code [i] would yield OA(382, 139, S3, 50), but
(82, 82+150, 360)-Net in Base 3 — Upper bound on s
There is no (82, 232, 361)-net in base 3, because
- the generalized Rao bound for nets shows that 3m ≥ 546 287409 037605 364691 145384 589499 580908 330559 932246 454690 883098 598907 686466 977987 300989 425021 942285 320391 411931 > 3232 [i]
