(100, 100+95, 217)-Net over F2 — Upper bound on s (digital)
There is no digital (100, 195, 218)-net over F2, because
- 3 times m-reduction [i] would yield digital (100, 192, 218)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2192, 218, F2, 92) (dual of [218, 26, 93]-code), but
- 2 times code embedding in larger space [i] would yield linear OA(2194, 220, F2, 92) (dual of [220, 26, 93]-code), but
- adding a parity check bit [i] would yield linear OA(2195, 221, F2, 93) (dual of [221, 26, 94]-code), but
- 2 times code embedding in larger space [i] would yield linear OA(2194, 220, F2, 92) (dual of [220, 26, 93]-code), but
- extracting embedded orthogonal array [i] would yield linear OA(2192, 218, F2, 92) (dual of [218, 26, 93]-code), but
(100, 100+95, 257)-Net in Base 2 — Upper bound on s
There is no (100, 195, 258)-net in base 2, because
- 1 times m-reduction [i] would yield (100, 194, 258)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 27659 720373 837776 883211 320505 037022 929276 914336 498339 654528 > 2194 [i]
