(82, 184, 174)-Net over F2 — Upper bound on s (digital)
There is no digital (82, 184, 175)-net over F2, because
- 18 times m-reduction [i] would yield digital (82, 166, 175)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2166, 175, F2, 84) (dual of [175, 9, 85]-code), but
- residual code [i] would yield linear OA(282, 90, F2, 42) (dual of [90, 8, 43]-code), but
- adding a parity check bit [i] would yield linear OA(283, 91, F2, 43) (dual of [91, 8, 44]-code), but
- “DMa†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(283, 91, F2, 43) (dual of [91, 8, 44]-code), but
- residual code [i] would yield linear OA(282, 90, F2, 42) (dual of [90, 8, 43]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2166, 175, F2, 84) (dual of [175, 9, 85]-code), but
(82, 184, 175)-Net in Base 2 — Upper bound on s
There is no (82, 184, 176)-net in base 2, because
