Linear OOA(3²⁴⁴, 148, F₃, 2, 123) (dual of [(148, 2), 52, 124]-NRT-code), using strength reduction based on linear OOA(3²⁴⁴, 148, F₃, 2, 124) (dual of [(148, 2), 52, 125]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OA(81²⁴, 37, F₈₁, 24) (dual of [37, 13, 25]-code or 37-arc in PG(23,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁴, 81, F₈₁, 24) (dual of [81, 57, 25]-code or 81-arc in PG(23,81)), using
    - Reedâ€“Solomon code RS(57,81) [i]
