(122, 131, large)-Net over F₂ — Digital

Digital (122, 131, large)-net over F₂, using

2¹⁴ 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

      - OOAs constructed from BCH codes [i]

(122, 131, large)-Net in Base 2 — Upper bound on s

There is no (122, 131, large)-net in base 2, because

7 times m-reduction [i] would yield (122, 124, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
