Information on Result #550860

There is no linear OOA(2⁶⁹, 71, F₂, 2, 38) (dual of [(71, 2), 73, 39]-NRT-code), because 6 step m-reduction would yield linear OA(2⁶³, 71, F₂, 32) (dual of [71, 8, 33]-code), but

residual code [i] would yield linear OA(2³¹, 38, F₂, 16) (dual of [38, 7, 17]-code), but
- residual code [i] would yield linear OA(2¹⁵, 21, F₂, 8) (dual of [21, 6, 9]-code), but
  - residual code [i] would yield linear OA(2⁷, 12, F₂, 4) (dual of [12, 5, 5]-code), but
    - bound by Fontaine and Peterson [i]

Mode: Bound (linear).
