Information on Result #554612

There is no linear OOA(2²³⁹, 236, F₂, 2, 127) (dual of [(236, 2), 233, 128]-NRT-code), because 15 step m-reduction would yield linear OA(2²²⁴, 236, F₂, 112) (dual of [236, 12, 113]-code), but

residual code [i] would yield linear OA(2¹¹², 123, F₂, 56) (dual of [123, 11, 57]-code), but
- residual code [i] would yield linear OA(2⁵⁶, 66, F₂, 28) (dual of [66, 10, 29]-code), but
  - adding a parity check bit [i] would yield linear OA(2⁵⁷, 67, F₂, 29) (dual of [67, 10, 30]-code), but
    - â€œJaâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
