(83, 160, 191)-Net over F2 — Upper bound on s (digital)
There is no digital (83, 160, 192)-net over F2, because
- 1 times m-reduction [i] would yield digital (83, 159, 192)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2159, 192, F2, 76) (dual of [192, 33, 77]-code), but
- 4 times code embedding in larger space [i] would yield linear OA(2163, 196, F2, 76) (dual of [196, 33, 77]-code), but
- adding a parity check bit [i] would yield linear OA(2164, 197, F2, 77) (dual of [197, 33, 78]-code), but
- 4 times code embedding in larger space [i] would yield linear OA(2163, 196, F2, 76) (dual of [196, 33, 77]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2159, 192, F2, 76) (dual of [192, 33, 77]-code), but
(83, 160, 221)-Net in Base 2 — Upper bound on s
There is no (83, 160, 222)-net in base 2, because
- 1 times m-reduction [i] would yield (83, 159, 222)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 791095 274832 259828 166625 892677 646787 828250 063800 > 2159 [i]
