        discarding factors / shortening the dual code based on linear OA(32³¹, large, F₃₂, 7) (dual of [large, large−31, 8]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 33554433Â | 32¹⁰âˆ’1, defining interval IÂ =Â [0,3], and minimum distance dÂ â‰¥ |{−3,−2,…,3}|+1Â =Â 8 (BCH-bound) [i]

(49−3, 49, large)-Net in Base 32 — Upper bound on s

There is no (46, 49, large)-net in base 32, because

1 times m-reduction [i] would yield (46, 48, large)-net in base 32, but
- mutually orthogonal hypercube bound [i]
