(146−8, 146, large)-Net over F₂ — Digital

Digital (138, 146, large)-net over F₂, using

2⁶ times duplication [i] based on digital (132, 140, large)-net over F₂, using
- t-expansion [i] based on digital (130, 140, large)-net over F₂, using

(146−8, 146, large)-Net in Base 2 — Upper bound on s

There is no (138, 146, large)-net in base 2, because

6 times m-reduction [i] would yield (138, 140, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
