- OOA 3-folding and stacking with additional row [i] based on linear OOA(6442, 4321, F64, 3, 18) (dual of [(4321, 3), 12921, 19]-NRT-code), using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(6442, 4321, F64, 18) (dual of [4321, 4279, 19]-code), using
- 216 step Varšamov–Edel lengthening with (ri) = (4, 4 times 0, 1, 15 times 0, 1, 50 times 0, 1, 143 times 0) [i] based on linear OA(6435, 4098, F64, 18) (dual of [4098, 4063, 19]-code), using
- construction X applied to Ce(17) ⊂ Ce(16) [i] based on
- linear OA(6435, 4096, F64, 18) (dual of [4096, 4061, 19]-code), using an extension Ce(17) of the primitive narrow-sense BCH-code C(I) with length 4095 = 642−1, defining interval I = [1,17], and designed minimum distance d ≥ |I|+1 = 18 [i]
