Linear OOA(470, 307, F4, 3, 22) (dual of [(307, 3), 851, 23]-NRT-code), using embedding of OOA with Gilbert–Varšamov bound based on linear OA(470, 307, F4, 22) (dual of [307, 237, 23]-code), using
- 40 step Varšamov–Edel lengthening with (ri) = (2, 1, 0, 1, 0, 0, 0, 1, 6 times 0, 1, 10 times 0, 1, 14 times 0) [i] based on linear OA(463, 260, F4, 22) (dual of [260, 197, 23]-code), using
- construction X applied to Ce(21) ⊂ Ce(20) [i] based on
