Digital (221, 256, 15425)-net over F4, using net defined by OOA based on linear OOA(4256, 15425, F4, 35, 35) (dual of [(15425, 35), 539619, 36]-NRT-code), using
- OOA 17-folding and stacking with additional row [i] based on linear OA(4256, 262226, F4, 35) (dual of [262226, 261970, 36]-code), using
- discarding factors / shortening the dual code based on linear OA(4256, 262228, F4, 35) (dual of [262228, 261972, 36]-code), using
- construction X applied to Ce(34) ⊂ Ce(25) [i] based on
- linear OA(4235, 262144, F4, 35) (dual of [262144, 261909, 36]-code), using an extension Ce(34) of the primitive narrow-sense BCH-code C(I) with length 262143 = 49−1, defining interval I = [1,34], and designed minimum distance d ≥ |I|+1 = 35 [i]
