Information on Result #550393

There is no linear OOA(16⁷, 945412, F₁₆, 2, 3) (dual of [(945412, 2), 1890817, 4]-NRT-code), because 1 times depth reduction would yield linear OA(16⁷, 945412, F₁₆, 3) (dual of [945412, 945405, 4]-code or 945412-cap in PG(6,16)), but

removing affine subspaces [i] would yield
1. linear OA(16⁵, 3934, F₁₆, 3) (dual of [3934, 3929, 4]-code or 3934-cap in PG(4,16)), but
  - bound for caps in PG(4,Â b) [i]
2. 58269-cap in AG(5,16), but
  - 2 times the recursive bound from Bierbrauer and Edel [i] would yield 257-cap in AG(3,16), but
    - affine subcap of ovoid is optimal [i]
3. 883211-cap in AG(6,16), but
  - 3 times the recursive bound from Bierbrauer and Edel [i] would yield 257-cap in AG(3,16) (see above)

Mode: Bound (linear).
