Information on Result #599782

There is no digital (5, 8, 74325)-net over F₇, because extracting embedded orthogonal array would yield linear OA(7⁸, 74325, F₇, 3) (dual of [74325, 74317, 4]-code or 74325-cap in PG(7,7)), but

removing affine subspaces [i] would yield
1. linear OA(7⁶, 1659, F₇, 3) (dual of [1659, 1653, 4]-code or 1659-cap in PG(5,7)), but
  - 1 times Hill recurrence [i] would yield linear OA(7⁵, 239, F₇, 3) (dual of [239, 234, 4]-code or 239-cap in PG(4,7)), but
    - a result by Edel, Storme, and Sziklai [i]
2. 9735-cap in AG(6,7), but
  - 2 times the recursive bound from Bierbrauer and Edel [i] would yield 239-cap in AG(4,7), but
    - embedding in projective space [i] would yield linear OA(7⁵, 239, F₇, 3) (dual of [239, 234, 4]-code or 239-cap in PG(4,7)) (see above)
3. 62933-cap in AG(7,7), but
  - 3 times the recursive bound from Bierbrauer and Edel [i] would yield 239-cap in AG(4,7) (see above)

Mode: Bound (linear).
