(158−9, 158, large)-Net over F₂ — Digital

Digital (149, 158, large)-net over F₂, using

2⁶ times duplication [i] based on digital (143, 152, large)-net over F₂, using
- t-expansion [i] based on digital (141, 152, large)-net over F₂, using

(158−9, 158, large)-Net in Base 2 — Upper bound on s

There is no (149, 158, large)-net in base 2, because

7 times m-reduction [i] would yield (149, 151, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
