(85, 175, 181)-Net over F2 — Upper bound on s (digital)
There is no digital (85, 175, 182)-net over F2, because
- 2 times m-reduction [i] would yield digital (85, 173, 182)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2173, 182, F2, 88) (dual of [182, 9, 89]-code), but
- residual code [i] would yield linear OA(285, 93, F2, 44) (dual of [93, 8, 45]-code), but
- residual code [i] would yield linear OA(241, 48, F2, 22) (dual of [48, 7, 23]-code), but
- residual code [i] would yield linear OA(219, 25, F2, 11) (dual of [25, 6, 12]-code), but
- 1 times truncation [i] would yield linear OA(218, 24, F2, 10) (dual of [24, 6, 11]-code), but
- residual code [i] would yield linear OA(28, 13, F2, 5) (dual of [13, 5, 6]-code), but
- 1 times truncation [i] would yield linear OA(27, 12, F2, 4) (dual of [12, 5, 5]-code), but
- residual code [i] would yield linear OA(28, 13, F2, 5) (dual of [13, 5, 6]-code), but

(85, 175, 201)-Net in Base 2 — Upper bound on s
There is no (85, 175, 202)-net in base 2, because
- the generalized Rao bound for nets shows that 2m ≥ 56794 654958 433460 615152 379789 760537 777087 947463 692560 > 2175 [i]
