Information on Result #563397
There is no linear OOA(8126, 265, F8, 2, 107) (dual of [(265, 2), 404, 108]-NRT-code), because 1 step m-reduction would yield linear OA(8125, 265, F8, 106) (dual of [265, 140, 107]-code), but
- construction Y1 [i] would yield
- OA(8124, 145, S8, 106), but
- the linear programming bound shows that M ≥ 1 342408 141203 687605 592802 609181 013836 865893 869002 996708 967389 151373 449322 112488 044923 320188 176348 763972 521547 313977 170182 155517 558784 / 126 646656 585020 246257 > 8124 [i]
- linear OA(8140, 265, F8, 120) (dual of [265, 125, 121]-code), but
- discarding factors / shortening the dual code would yield linear OA(8140, 260, F8, 120) (dual of [260, 120, 121]-code), but
- residual code [i] would yield OA(820, 139, S8, 15), but
- 1 times truncation [i] would yield OA(819, 138, S8, 14), but
- the linear programming bound shows that M ≥ 411449 038157 955600 826236 928000 / 2 816739 543071 > 819 [i]
- 1 times truncation [i] would yield OA(819, 138, S8, 14), but
- residual code [i] would yield OA(820, 139, S8, 15), but
- discarding factors / shortening the dual code would yield linear OA(8140, 260, F8, 120) (dual of [260, 120, 121]-code), but
- OA(8124, 145, S8, 106), but
Mode: Bound (linear).
