Digital (146, 172, 20165)-net over F₄, using net defined by OOA based on linear OOA(4¹⁷², 20165, F₄, 26, 26) (dual of [(20165, 26), 524118, 27]-NRT-code), using

OA 13-folding and stacking [i] based on linear OA(4¹⁷², 262145, F₄, 26) (dual of [262145, 261973, 27]-code), using
- discarding factors / shortening the dual code based on linear OA(4¹⁷², 262153, F₄, 26) (dual of [262153, 261981, 27]-code), using
  - constructionÂ X applied to C_e(25) âŠ‚ C_e(24) [i] based on
    1. linear OA(4¹⁷², 262144, F₄, 26) (dual of [262144, 261972, 27]-code), using an extension C_e(25) of the primitive narrow-sense BCH-code C(I) with length 262143Â = 4⁹âˆ’1, defining interval IÂ =Â [1,25], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 26 [i]
