Linear OA(6444, 77, F64, 33) (dual of [77, 33, 34]-code), using construction X applied to C([0,16]) ⊂ C([1,16]) based on
  1. linear OA(6433, 65, F64, 33) (dual of [65, 32, 34]-code or 65-arc in PG(32,64)), using the expurgated narrow-sense BCH-code C(I) with length 65 | 642−1, defining interval I = [0,16], and minimum distance d ≥ |{−16,−15,…,16}|+1 = 34 (BCH-bound) [i]
  2. linear OA(6432, 65, F64, 21) (dual of [65, 33, 22]-code), using the narrow-sense BCH-code C(I) with length 65 | 642−1, defining interval I = [1,16], and minimum distance d ≥ |{1,2,…,11}| + |{5,21,37,…,0}∖{−32,17,−31,18,−30,19,−29,20,−28,21}| = 22 (general Roos-bound) [i]
