        OOA 3-folding [i] based on linear OA(64²⁵, large, F₆₄, 7) (dual of [large, large−25, 8]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 16777217Â | 64⁸âˆ’1, defining interval IÂ =Â [0,3], and minimum distance dÂ â‰¥ |{−3,−2,…,3}|+1Â =Â 8 (BCH-bound) [i]

(78−5, 78, large)-Net in Base 8 — Upper bound on s

There is no (73, 78, large)-net in base 8, because

3 times m-reduction [i] would yield (73, 75, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
