(53, 60, large)-Net over F₈ — Digital

Digital (53, 60, large)-net over F₈, using

8² times duplication [i] based on digital (51, 58, large)-net over F₈, using
- t-expansion [i] based on digital (49, 58, large)-net over F₈, using
  - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(8⁵⁸, large, F₈, 9) (dual of [large, large−58, 10]-code), using

(53, 60, large)-Net in Base 8 — Upper bound on s

There is no (53, 60, large)-net in base 8, because

5 times m-reduction [i] would yield (53, 55, large)-net in base 8, but
- mutually orthogonal hypercube bound [i]
