(184−97, 184, 184)-Net over F2 — Upper bound on s (digital)
There is no digital (87, 184, 185)-net over F2, because
- 9 times m-reduction [i] would yield digital (87, 175, 185)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2175, 185, F2, 88) (dual of [185, 10, 89]-code), but
- residual code [i] would yield linear OA(287, 96, F2, 44) (dual of [96, 9, 45]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2175, 185, F2, 88) (dual of [185, 10, 89]-code), but
(184−97, 184, 186)-Net in Base 2 — Upper bound on s
There is no (87, 184, 187)-net in base 2, because
- 3 times m-reduction [i] would yield (87, 181, 187)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2181, 187, S2, 94), but
- the (dual) Plotkin bound shows that M ≥ 294 239143 846250 660804 802629 212859 363254 797911 459251 617792 / 95 > 2181 [i]
- extracting embedded orthogonal array [i] would yield OA(2181, 187, S2, 94), but
