t-expansion [i] based on digital (42, 49, large)-net over F₂₇, using
- (u,Â u+v)-construction [i] based on
  1. digital (6, 9, large)-net over F₂₇, using
    - net defined by OOA [i] based on linear OOA(27⁹, large, F₂₇, 3, 3), using
      - appending kth column [i] based on linear OOA(27⁹, large, F₂₇, 2, 3), using
        OAs with strength 3, bÂ â‰ Â 2, and mÂ >Â 3 are always embeddable [i] based on linear OA(27⁹, large, F₂₇, 3) (dual of [large, large−9, 4]-code), using
        product of projective cap with (hyper)oval [i] based on linear OA(27⁷, 532899, F₂₇, 3) (dual of [532899, 532892, 4]-code or 532899-cap in PG(6,27)), using
        product of two caps with tangent hyperplane [i]
  2. digital (33, 40, 5592400)-net over F₂₇, using
