Information on Result #551951

There is no linear OOA(2¹⁴¹, 144, F₂, 2, 74) (dual of [(144, 2), 147, 75]-NRT-code), because 6 step m-reduction would yield linear OA(2¹³⁵, 144, F₂, 68) (dual of [144, 9, 69]-code), but

residual code [i] would yield linear OA(2⁶⁷, 75, F₂, 34) (dual of [75, 8, 35]-code), but
- adding a parity check bit [i] would yield linear OA(2⁶⁸, 76, F₂, 35) (dual of [76, 8, 36]-code), but
  - â€œBJVâ€ bound on codes from Brouwerâ€™s database [i]

Mode: Bound (linear).
