Digital (217, 236, 1398147)-net over F₂, using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OOA(2²³⁶, 1398147, F₂, 6, 19) (dual of [(1398147, 6), 8388646, 20]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(2²⁸, 47, F₂, 6, 9) (dual of [(47, 6), 254, 10]-NRT-code), using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(2²⁸, 47, F₂, 2, 9) (dual of [(47, 2), 66, 10]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(2²⁸, 94, F₂, 9) (dual of [94, 66, 10]-code), using
      - discarding factors / shortening the dual code based on linear OA(2²⁸, 95, F₂, 9) (dual of [95, 67, 10]-code), using
        adding a parity check bit [i] based on linear OA(2²⁷, 94, F₂, 8) (dual of [94, 67, 9]-code), using
        a â€œGraâ€ code from Grasslâ€™s database [i]
2. linear OOA(2²⁰⁸, 1398100, F₂, 6, 19) (dual of [(1398100, 6), 8388392, 20]-NRT-code), using
  - OOA 6-folding [i] based on linear OA(2²⁰⁸, 8388600, F₂, 19) (dual of [8388600, 8388392, 20]-code), using
    - discarding factors / shortening the dual code based on linear OA(2²⁰⁸, large, F₂, 19) (dual of [large, large−208, 20]-code), using
