(107, 206, 266)-Net over F2 — Upper bound on s (digital)
There is no digital (107, 206, 267)-net over F2, because
- 1 times m-reduction [i] would yield digital (107, 205, 267)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2205, 267, F2, 98) (dual of [267, 62, 99]-code), but
- construction Y1 [i] would yield
- linear OA(2204, 245, F2, 98) (dual of [245, 41, 99]-code), but
- residual code [i] would yield OA(2106, 146, S2, 49), but
- 1 times truncation [i] would yield OA(2105, 145, S2, 48), but
- the linear programming bound shows that M ≥ 727 070369 678229 731686 401086 929362 121333 407744 / 17 521374 765895 > 2105 [i]
- 1 times truncation [i] would yield OA(2105, 145, S2, 48), but
- residual code [i] would yield OA(2106, 146, S2, 49), but
- OA(262, 267, S2, 22), but
- discarding factors would yield OA(262, 249, S2, 22), but
- the Rao or (dual) Hamming bound shows that M ≥ 4 787396 297110 060300 > 262 [i]
- discarding factors would yield OA(262, 249, S2, 22), but
- linear OA(2204, 245, F2, 98) (dual of [245, 41, 99]-code), but
- construction Y1 [i] would yield
- extracting embedded orthogonal array [i] would yield linear OA(2205, 267, F2, 98) (dual of [267, 62, 99]-code), but
(107, 206, 280)-Net in Base 2 — Upper bound on s
There is no (107, 206, 281)-net in base 2, because
- 1 times m-reduction [i] would yield (107, 205, 281)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 54 350550 802541 054223 530507 370859 578045 476006 923795 244013 180144 > 2205 [i]
