Information on Result #526574
There is no linear OA(78, 74325, F7, 3) (dual of [74325, 74317, 4]-code or 74325-cap in PG(7,7)), because removing affine subspaces would yield
- linear OA(76, 1659, F7, 3) (dual of [1659, 1653, 4]-code or 1659-cap in PG(5,7)), but
- 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
- 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).
