(128, 128+9, large)-Net over F₂ — Digital

Digital (128, 137, large)-net over F₂, using

2²⁰ times duplication [i] based on digital (108, 117, large)-net over F₂, using
- net defined by OOA [i] based on linear OOA(2¹¹⁷, large, F₂, 9, 9), using
  - appending kth column [i] based on linear OOA(2¹¹⁷, large, F₂, 8, 9), using

(128, 128+9, large)-Net in Base 2 — Upper bound on s

There is no (128, 137, large)-net in base 2, because

7 times m-reduction [i] would yield (128, 130, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
