(167−83, 167, 186)-Net over F2 — Upper bound on s (digital)
There is no digital (84, 167, 187)-net over F2, because
- 1 times m-reduction [i] would yield digital (84, 166, 187)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2166, 187, F2, 82) (dual of [187, 21, 83]-code), but
- residual code [i] would yield linear OA(284, 104, F2, 41) (dual of [104, 20, 42]-code), but
- “Bro†bound on codes from Brouwer’s database [i]
- residual code [i] would yield linear OA(284, 104, F2, 41) (dual of [104, 20, 42]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2166, 187, F2, 82) (dual of [187, 21, 83]-code), but
(167−83, 167, 211)-Net in Base 2 — Upper bound on s
There is no (84, 167, 212)-net in base 2, because
- 1 times m-reduction [i] would yield (84, 166, 212)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 96 566697 296403 102515 495902 319018 075759 398818 418620 > 2166 [i]
