(155−8, 155, large)-Net over F₂ — Digital

Digital (147, 155, large)-net over F₂, using

2³ times duplication [i] based on digital (144, 152, large)-net over F₂, using
- t-expansion [i] based on digital (141, 152, large)-net over F₂, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(2¹⁵², large, F₂, 3, 11), using

(155−8, 155, large)-Net in Base 2 — Upper bound on s

There is no (147, 155, large)-net in base 2, because

6 times m-reduction [i] would yield (147, 149, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
