(20, 26, 2812585)-net in base 64, using net defined by OOA based on OOA(64²⁶, 2812585, S₆₄, 9, 6), using

OOA stacking with additional row [i] based on OOA(64²⁶, 2812586, S₆₄, 3, 6), using
- (u,Â u+v)-construction [i] based on
  1. OOA(64⁵, 16385, S₆₄, 3, 3), using
    - appending kth column [i] based on OOA(64⁵, 16385, S₆₄, 2, 3), using
      - discarding parts of the base [i] based on linear OOA(128⁴, 16385, F₁₂₈, 2, 3) (dual of [(16385, 2), 32766, 4]-NRT-code), using
