(18, 31, 2731)-net in base 64, using net defined by OOA based on OOA(6431, 2731, S64, 13, 13), using
- OOA 6-folding and stacking with additional row [i] based on OA(6431, 16387, S64, 13), using
- discarding factors based on OA(6431, 16390, S64, 13), using
- discarding parts of the base [i] based on linear OA(12826, 16390, F128, 13) (dual of [16390, 16364, 14]-code), using
- construction X applied to C([0,6]) ⊂ C([0,5]) [i] based on
- linear OA(12825, 16385, F128, 13) (dual of [16385, 16360, 14]-code), using the expurgated narrow-sense BCH-code C(I) with length 16385 | 1284−1, defining interval I = [0,6], and minimum distance d ≥ |{−6,−5,…,6}|+1 = 14 (BCH-bound) [i]
