Linear OOA(220, 261, F2, 2, 5) (dual of [(261, 2), 502, 6]-NRT-code), using OOA 2-folding based on linear OA(220, 522, F2, 5) (dual of [522, 502, 6]-code), using
- construction X applied to Ce(4) ⊂ Ce(2) [i] based on
- linear OA(219, 512, F2, 5) (dual of [512, 493, 6]-code), using an extension Ce(4) of the primitive narrow-sense BCH-code C(I) with length 511 = 29−1, defining interval I = [1,4], and designed minimum distance d ≥ |I|+1 = 5 [i]
- linear OA(210, 512, F2, 3) (dual of [512, 502, 4]-code or 512-cap in PG(9,2)), using an extension Ce(2) of the primitive narrow-sense BCH-code C(I) with length 511 = 29−1, defining interval I = [1,2], and designed minimum distance d ≥ |I|+1 = 3 [i]
