(13, 21, 1641)-net in base 27, using net defined by OOA based on OOA(2721, 1641, S27, 8, 8), using
- OA 4-folding and stacking [i] based on OA(2721, 6564, S27, 8), using
- 1 times code embedding in larger space [i] based on OA(2720, 6563, S27, 8), using
- discarding parts of the base [i] based on linear OA(8115, 6563, F81, 8) (dual of [6563, 6548, 9]-code), using
- construction X applied to Ce(7) ⊂ Ce(6) [i] based on
- linear OA(8115, 6561, F81, 8) (dual of [6561, 6546, 9]-code), using an extension Ce(7) of the primitive narrow-sense BCH-code C(I) with length 6560 = 812−1, defining interval I = [1,7], and designed minimum distance d ≥ |I|+1 = 8 [i]
