(85, 170, 183)-Net over F2 — Upper bound on s (digital)
There is no digital (85, 170, 184)-net over F2, because
- 1 times m-reduction [i] would yield digital (85, 169, 184)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2169, 184, F2, 84) (dual of [184, 15, 85]-code), but
- residual code [i] would yield linear OA(285, 99, F2, 42) (dual of [99, 14, 43]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2169, 184, F2, 84) (dual of [184, 15, 85]-code), but
(85, 170, 211)-Net in Base 2 — Upper bound on s
There is no (85, 170, 212)-net in base 2, because
- 1 times m-reduction [i] would yield (85, 169, 212)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 748 602885 726626 685565 542852 092854 259812 380644 506020 > 2169 [i]
