(200−104, 200, 201)-Net over F2 — Upper bound on s (digital)
There is no digital (96, 200, 202)-net over F2, because
- 8 times m-reduction [i] would yield digital (96, 192, 202)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2192, 202, F2, 96) (dual of [202, 10, 97]-code), but
- residual code [i] would yield linear OA(296, 105, F2, 48) (dual of [105, 9, 49]-code), but
- residual code [i] would yield linear OA(248, 56, F2, 24) (dual of [56, 8, 25]-code), but
- adding a parity check bit [i] would yield linear OA(249, 57, F2, 25) (dual of [57, 8, 26]-code), but
- “BJV†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(249, 57, F2, 25) (dual of [57, 8, 26]-code), but
- residual code [i] would yield linear OA(248, 56, F2, 24) (dual of [56, 8, 25]-code), but

- extracting embedded orthogonal array [i] would yield linear OA(2192, 202, F2, 96) (dual of [202, 10, 97]-code), but
(200−104, 200, 204)-Net in Base 2 — Upper bound on s
There is no (96, 200, 205)-net in base 2, because
- 2 times m-reduction [i] would yield (96, 198, 205)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2198, 205, S2, 102), but
- adding a parity check bit [i] would yield OA(2199, 206, S2, 103), but
- the (dual) Plotkin bound shows that M ≥ 12 855504 354071 922204 335696 738729 300820 177623 950262 342682 411008 / 13 > 2199 [i]
