(27, 48, 1638)-net in base 64, using net defined by OOA based on OOA(6448, 1638, S64, 21, 21), using
- OOA 10-folding and stacking with additional row [i] based on OA(6448, 16381, S64, 21), using
- discarding factors based on OA(6448, 16386, S64, 21), using
- discarding parts of the base [i] based on linear OA(12841, 16386, F128, 21) (dual of [16386, 16345, 22]-code), using
- construction X applied to Ce(20) ⊂ Ce(19) [i] based on
- linear OA(12841, 16384, F128, 21) (dual of [16384, 16343, 22]-code), using an extension Ce(20) of the primitive narrow-sense BCH-code C(I) with length 16383 = 1282−1, defining interval I = [1,20], and designed minimum distance d ≥ |I|+1 = 21 [i]
