(148−9, 148, large)-Net over F₂ — Digital

Digital (139, 148, large)-net over F₂, using

2⁸ times duplication [i] based on digital (131, 140, large)-net over F₂, using
- t-expansion [i] based on digital (130, 140, large)-net over F₂, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(2¹⁴⁰, large, F₂, 3, 10), using

(148−9, 148, large)-Net in Base 2 — Upper bound on s

There is no (139, 148, large)-net in base 2, because

7 times m-reduction [i] would yield (139, 141, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
