        discarding factors / shortening the dual code based on linear OA(25¹⁶, large, F₂₅, 4) (dual of [large, large−16, 5]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 9765624Â = 25⁵âˆ’1, defining interval IÂ =Â [0,3], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 5 [i]

(59−9, 59, large)-Net over F₂₅ — Digital

Digital (50, 59, large)-net over F₂₅, using

t-expansion [i] based on digital (48, 59, large)-net over F₂₅, using
- 2 times m-reduction [i] based on digital (48, 61, large)-net over F₂₅, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(25⁶¹, large, F₂₅, 13) (dual of [large, large−61, 14]-code), using
    - the expurgated narrow-sense BCH-code C(I) with length 9765626Â | 25¹⁰âˆ’1, defining interval IÂ =Â [0,6], and minimum distance dÂ â‰¥ |{−6,−5,…,6}|+1Â =Â 14 (BCH-bound) [i]

(59−9, 59, large)-Net in Base 25 — Upper bound on s

There is no (50, 59, large)-net in base 25, because

7 times m-reduction [i] would yield (50, 52, large)-net in base 25, but
- mutually orthogonal hypercube bound [i]
