        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 64⁴âˆ’1, defining interval IÂ =Â [0,13], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 15 [i]

(147, 161, large)-Net over F₈ — Digital

Digital (147, 161, large)-net over F₈, using

t-expansion [i] based on digital (144, 161, large)-net over F₈, using
- 7 times m-reduction [i] based on digital (144, 168, large)-net over F₈, using

(147, 161, large)-Net in Base 8 — Upper bound on s

There is no (147, 161, large)-net in base 8, because

12 times m-reduction [i] would yield (147, 149, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
