Linear OOA(954, 487, F9, 2, 18) (dual of [(487, 2), 920, 19]-NRT-code), using OOA 2-folding based on linear OA(954, 974, F9, 18) (dual of [974, 920, 19]-code), using
- discarding factors / shortening the dual code based on linear OA(954, 975, F9, 18) (dual of [975, 921, 19]-code), using
- 240 step Varšamov–Edel lengthening with (ri) = (2, 4 times 0, 1, 14 times 0, 1, 38 times 0, 1, 73 times 0, 1, 106 times 0) [i] based on linear OA(948, 729, F9, 18) (dual of [729, 681, 19]-code), using
- 1 times truncation [i] based on linear OA(949, 730, F9, 19) (dual of [730, 681, 20]-code), using
