Digital (44, 49, large)-net over F₂₅, using t-expansion based on digital (42, 49, large)-net over F₂₅, using

(u,Â u+v)-construction [i] based on
1. digital (6, 9, large)-net over F₂₅, using
  - net defined by OOA [i] based on linear OOA(25⁹, large, F₂₅, 3, 3), using
    - appending kth column [i] based on linear OOA(25⁹, large, F₂₅, 2, 3), using
      - OAs with strength 3, bÂ â‰ Â 2, and mÂ >Â 3 are always embeddable [i] based on linear OA(25⁹, large, F₂₅, 3) (dual of [large, large−9, 4]-code), using
        product of projective cap with (hyper)oval [i] based on linear OA(25⁷, 391875, F₂₅, 3) (dual of [391875, 391868, 4]-code or 391875-cap in PG(6,25)), using
        product of two caps with tangent hyperplane [i]
2. digital (33, 40, 5592400)-net over F₂₅, using
  - (u,Â u+v)-construction [i] based on
    1. digital (6, 9, large)-net over F₂₅ (see above)
    2. digital (24, 31, 2796200)-net over F₂₅, using
      - net defined by OOA [i] based on linear OOA(25³¹, 2796200, F₂₅, 7, 7) (dual of [(2796200, 7), 19573369, 8]-NRT-code), using
        OOA 3-folding and stacking with additional row [i] based on linear OA(25³¹, 8388601, F₂₅, 7) (dual of [8388601, 8388570, 8]-code), using
        discarding factors / shortening the dual code based on linear OA(25³¹, large, F₂₅, 7) (dual of [large, large−31, 8]-code), using
