Information on Result #555088

There is no linear OOA(2²⁵⁵, 240, F₂, 2, 141) (dual of [(240, 2), 225, 142]-NRT-code), because 25 step m-reduction would yield linear OA(2²³⁰, 240, F₂, 116) (dual of [240, 10, 117]-code), but

residual code [i] would yield linear OA(2¹¹⁴, 123, F₂, 58) (dual of [123, 9, 59]-code), but
- residual code [i] would yield linear OA(2⁵⁶, 64, F₂, 29) (dual of [64, 8, 30]-code), but
  - 1 times truncation [i] would yield linear OA(2⁵⁵, 63, F₂, 28) (dual of [63, 8, 29]-code), but
    - â€œBJVâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
