net defined by OOA [i] based on linear OOA(3¹⁶¹, 177150, F₃, 19, 19) (dual of [(177150, 19), 3365689, 20]-NRT-code), using
- OOA 9-folding and stacking with additional row [i] based on linear OA(3¹⁶¹, 1594351, F₃, 19) (dual of [1594351, 1594190, 20]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹⁶¹, 1594353, F₃, 19) (dual of [1594353, 1594192, 20]-code), using
    - constructionÂ X applied to C_e(18) âŠ‚ C_e(15) [i] based on
      1. linear OA(3¹⁵⁷, 1594323, F₃, 19) (dual of [1594323, 1594166, 20]-code), using an extension C_e(18) of the primitive narrow-sense BCH-code C(I) with length 1594322Â = 3¹³âˆ’1, defining interval IÂ =Â [1,18], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 19 [i]
