(21, 30, 524288)-net in base 64, using net defined by OOA based on OOA(6430, 524288, S64, 9, 9), using
- OOA 4-folding and stacking with additional row [i] based on OA(6430, 2097153, S64, 9), using
- discarding factors based on OA(6430, 2097155, S64, 9), using
- discarding parts of the base [i] based on linear OA(12825, 2097155, F128, 9) (dual of [2097155, 2097130, 10]-code), using
- construction X applied to Ce(8) ⊂ Ce(7) [i] based on
- linear OA(12825, 2097152, F128, 9) (dual of [2097152, 2097127, 10]-code), using an extension Ce(8) of the primitive narrow-sense BCH-code C(I) with length 2097151 = 1283−1, defining interval I = [1,8], and designed minimum distance d ≥ |I|+1 = 9 [i]
