(52, 85, 480)-Net over F₈ — Digital

Digital (52, 85, 480)-net over F₈, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(8⁸⁵, 480, F₈, 33) (dual of [480, 395, 34]-code), using
- discarding factors / shortening the dual code based on linear OA(8⁸⁵, 511, F₈, 33) (dual of [511, 426, 34]-code), using
  - the primitive expurgated narrow-sense BCH-code C(I) with length 511Â = 8³âˆ’1, defining interval IÂ =Â [0,32], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 34 [i]

(52, 85, 53528)-Net in Base 8 — Upper bound on s

There is no (52, 85, 53529)-net in base 8, because

1 times m-reduction [i] would yield (52, 84, 53529)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 7238 444426 643139 988693 807785 933431 531534 230461 456633 437213 016096 220816 410623 > 8⁸⁴ [i]
