Information on Result #555297

There is no linear OOA(3²⁷, 31, F₃, 2, 19) (dual of [(31, 2), 35, 20]-NRT-code), because 1 step m-reduction would yield linear OA(3²⁶, 31, F₃, 18) (dual of [31, 5, 19]-code), but

residual code [i] would yield linear OA(3⁸, 12, F₃, 6) (dual of [12, 4, 7]-code), but
- residual code [i] would yield linear OA(3², 5, F₃, 2) (dual of [5, 3, 3]-code or 5-arc in PG(1,3)), but
  - improvement by Maruta on the Griesmer bound [i]

Mode: Bound (linear).
