  1. linear OA(237, 513, F2, 9) (dual of [513, 476, 10]-code), using the expurgated narrow-sense BCH-code C(I) with length 513 | 218−1, defining interval I = [0,4], and minimum distance d ≥ |{−4,−3,…,4}|+1 = 10 (BCH-bound) [i]
  2. linear OA(236, 513, F2, 6) (dual of [513, 477, 7]-code), using the narrow-sense BCH-code C(I) with length 513 | 218−1, defining interval I = [1,4], and minimum distance d ≥ |{1,2,3,4}| + |{0,254,508}| = 7 (simple Roos-bound) [i]
