  1. linear OA(4³⁵, 341, F₄, 10) (dual of [341, 306, 11]-code), using the BCH-code C(I) with length 341Â | 4⁵âˆ’1, defining interval IÂ =Â {106,107,…,115}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]
  2. linear OA(4³⁰, 341, F₄, 9) (dual of [341, 311, 10]-code), using the BCH-code C(I) with length 341Â | 4⁵âˆ’1, defining interval IÂ =Â {107,108,…,115}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 10 [i]
  3. linear OA(4⁰, 5, F₄, 0) (dual of [5, 5, 1]-code), using
    - discarding factors / shortening the dual code based on linear OA(4⁰, s, F₄, 0) (dual of [s, s, 1]-code) with arbitrarily large s, using

(25, 35, 14224)-Net in Base 4 — Upper bound on s

There is no (25, 35, 14225)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1180 989389 586469 258336 > 4³⁵ [i]
