(82, 160, 188)-Net over F2 — Upper bound on s (digital)
There is no digital (82, 160, 189)-net over F2, because
- extracting embedded orthogonal array [i] would yield linear OA(2160, 189, F2, 78) (dual of [189, 29, 79]-code), but
- 6 times code embedding in larger space [i] would yield linear OA(2166, 195, F2, 78) (dual of [195, 29, 79]-code), but
- adding a parity check bit [i] would yield linear OA(2167, 196, F2, 79) (dual of [196, 29, 80]-code), but
- 6 times code embedding in larger space [i] would yield linear OA(2166, 195, F2, 78) (dual of [195, 29, 79]-code), but
(82, 160, 211)-Net in Base 2 — Upper bound on s
There is no (82, 160, 212)-net in base 2, because
- the generalized Rao bound for nets shows that 2m ≥ 1 530096 191591 810865 400299 649862 196970 817145 371640 > 2160 [i]
