Linear OOA(458, 293, F4, 3, 18) (dual of [(293, 3), 821, 19]-NRT-code), using embedding of OOA with Gilbert–Varšamov bound based on linear OA(458, 293, F4, 18) (dual of [293, 235, 19]-code), using
- 28 step Varšamov–Edel lengthening with (ri) = (3, 1, 0, 0, 1, 0, 0, 0, 1, 7 times 0, 1, 11 times 0) [i] based on linear OA(451, 258, F4, 18) (dual of [258, 207, 19]-code), using
- construction X applied to Ce(17) ⊂ Ce(16) [i] based on
- linear OA(451, 256, F4, 18) (dual of [256, 205, 19]-code), using an extension Ce(17) of the primitive narrow-sense BCH-code C(I) with length 255 = 44−1, defining interval I = [1,17], and designed minimum distance d ≥ |I|+1 = 18 [i]
