Linear OA(3²¹², 220, F₃, 136) (dual of [220, 8, 137]-code), using strength reduction based on linear OA(3²¹², 220, F₃, 137) (dual of [220, 8, 138]-code), using

concatenation of two codes [i] based on
1. linear OA(9⁵¹, 55, F₉, 45) (dual of [55, 4, 46]-code), using
  - a quasi-cyclic code by Bierbrauer and Gulliver [i]
2. linear OA(3², 4, F₃, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,3)), using
  - extended Reedâ€“Solomon code RS_e(2,3) [i]
  - Hamming code H(2,3) [i]
  - Simplex code S(2,3) [i]
  - the Tetracode [i]
