There is no linear OOA(9120, 254, F9, 2, 104) (dual of [(254, 2), 388, 105]-NRT-code), because 1 times depth reduction would yield linear OA(9120, 254, F9, 104) (dual of [254, 134, 105]-code), but
- construction Y1 [i] would yield
- OA(9119, 137, S9, 104), but
- the linear programming bound shows that M ≥ 1 649743 959172 993378 210906 967412 042627 075594 345401 873516 549288 005769 316925 057707 239007 022709 124331 368314 618099 062045 429872 721572 150117 / 4 003686 893566 937500 > 9119 [i]
- linear OA(9134, 254, F9, 117) (dual of [254, 120, 118]-code), but
- discarding factors / shortening the dual code would yield linear OA(9134, 251, F9, 117) (dual of [251, 117, 118]-code), but
- residual code [i] would yield OA(917, 133, S9, 13), but
- 1 times truncation [i] would yield OA(916, 132, S9, 12), but
- the linear programming bound shows that M ≥ 366759 481988 110308 514537 173543 / 191 274702 307783 > 916 [i]
- 1 times truncation [i] would yield OA(916, 132, S9, 12), but
- residual code [i] would yield OA(917, 133, S9, 13), but
- discarding factors / shortening the dual code would yield linear OA(9134, 251, F9, 117) (dual of [251, 117, 118]-code), but
- OA(9119, 137, S9, 104), but
Mode: Bound (linear).
