Information on Result #666308

Linear OA(2568, 15833, F25, 18) (dual of [15833, 15765, 19]-code), using (u, u+v)-construction based on
  1. linear OA(2516, 208, F25, 9) (dual of [208, 192, 10]-code), using
    • the BCH-code C(I) with length 208 | 252−1, defining interval I = {1,4,7,…,25}, and designed minimum distance d ≥ |I|+1 = 10 [i]
  2. linear OA(2552, 15625, F25, 18) (dual of [15625, 15573, 19]-code), using
    • an extension Ce(17) of the primitive narrow-sense BCH-code C(I) with length 15624 = 253−1, defining interval I = [1,17], and designed minimum distance d ≥ |I|+1 = 18 [i]
