(30, 51, 1639)-net in base 64, using 641 times duplication based on (29, 50, 1639)-net in base 64, using
- net defined by OOA [i] based on OOA(6450, 1639, S64, 21, 21), using
- OOA 10-folding and stacking with additional row [i] based on OA(6450, 16391, S64, 21), using
- 1 times code embedding in larger space [i] based on OA(6449, 16390, S64, 21), using
- discarding parts of the base [i] based on linear OA(12842, 16390, F128, 21) (dual of [16390, 16348, 22]-code), using
- construction X applied to C([0,10]) ⊂ C([0,9]) [i] based on
- linear OA(12841, 16385, F128, 21) (dual of [16385, 16344, 22]-code), using the expurgated narrow-sense BCH-code C(I) with length 16385 | 1284−1, defining interval I = [0,10], and minimum distance d ≥ |{−10,−9,…,10}|+1 = 22 (BCH-bound) [i]
