(97, 97+101, 204)-Net over F2 — Upper bound on s (digital)
There is no digital (97, 198, 205)-net over F2, because
- 3 times m-reduction [i] would yield digital (97, 195, 205)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2195, 205, F2, 98) (dual of [205, 10, 99]-code), but
- residual code [i] would yield linear OA(297, 106, F2, 49) (dual of [106, 9, 50]-code), but
- 1 times truncation [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
- 1 times truncation [i] would yield linear OA(296, 105, F2, 48) (dual of [105, 9, 49]-code), but

- extracting embedded orthogonal array [i] would yield linear OA(2195, 205, F2, 98) (dual of [205, 10, 99]-code), but
(97, 97+101, 207)-Net in Base 2 — Upper bound on s
There is no (97, 198, 208)-net in base 2, because
- 1 times m-reduction [i] would yield (97, 197, 208)-net in base 2, but
- extracting embedded orthogonal array [i] would yield OA(2197, 208, S2, 100), but
- the linear programming bound shows that M ≥ 8137 534256 127526 755344 496035 615647 419172 435960 516062 917966 168064 / 32147 > 2197 [i]
- extracting embedded orthogonal array [i] would yield OA(2197, 208, S2, 100), but
