Linear OOA(7⁵⁶, 30, F₇, 2, 47) (dual of [(30, 2), 4, 48]-NRT-code), using strength reduction based on linear OOA(7⁵⁶, 30, F₇, 2, 48) (dual of [(30, 2), 4, 49]-NRT-code), using

OOA 2-folding [i] based on linear OA(7⁵⁶, 60, F₇, 48) (dual of [60, 4, 49]-code), using
- constructionÂ X applied to C₁ âŠ‚ C₂ with C₁ a [50,1,49]-code [i] based on
  1. linear OA(7⁴⁶, 50, F₇, 41) (dual of [50, 4, 42]-code), using projective code from ovoid in PG(3,Â 7) [i]
