Linear OOA(468, 321, F4, 2, 21) (dual of [(321, 2), 574, 22]-NRT-code), using embedding of OOA with Gilbert–Varšamov bound based on linear OA(468, 321, F4, 21) (dual of [321, 253, 22]-code), using
- 56 step Varšamov–Edel lengthening with (ri) = (3, 1, 0, 1, 4 times 0, 1, 6 times 0, 1, 9 times 0, 1, 13 times 0, 1, 16 times 0) [i] based on linear OA(459, 256, F4, 21) (dual of [256, 197, 22]-code), using
- an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
