Linear OOA(32⁷⁷, large, F₃₂, 2, 9), using 10 times NRT-code embedding in larger space based on linear OOA(32⁵⁷, 8388602, F₃₂, 2, 9) (dual of [(8388602, 2), 16777147, 10]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(32¹⁶, 4194301, F₃₂, 2, 4) (dual of [(4194301, 2), 8388586, 5]-NRT-code), using
  - OOA 2-folding [i] based on linear OA(32¹⁶, 8388602, F₃₂, 4) (dual of [8388602, 8388586, 5]-code), using
    - discarding factors / shortening the dual code based on linear OA(32¹⁶, large, F₃₂, 4) (dual of [large, large−16, 5]-code), using
