Linear OOA(4103, 2121, F4, 3, 21) (dual of [(2121, 3), 6260, 22]-NRT-code), using OOA 2-folding based on linear OOA(4103, 4242, F4, 2, 21) (dual of [(4242, 2), 8381, 22]-NRT-code), using
- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OA(4103, 4242, F4, 21) (dual of [4242, 4139, 22]-code), using
- 134 step Varšamov–Edel lengthening with (ri) = (4, 1, 1, 0, 0, 1, 4 times 0, 1, 7 times 0, 1, 12 times 0, 1, 19 times 0, 1, 32 times 0, 1, 49 times 0) [i] based on linear OA(491, 4096, F4, 21) (dual of [4096, 4005, 22]-code), using
- an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 4095 = 46−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
