(6, 6+85, 149)-Net over F16 — Upper bound on s (digital)
There is no digital (6, 91, 150)-net over F16, because
- 1 times m-reduction [i] would yield digital (6, 90, 150)-net over F16, but
- extracting embedded orthogonal array [i] would yield linear OA(1690, 150, F16, 84) (dual of [150, 60, 85]-code), but
- construction Y1 [i] would yield
- linear OA(1689, 94, F16, 84) (dual of [94, 5, 85]-code), but
- construction Y1 [i] would yield
- OA(1688, 90, S16, 84), but
- 4 times truncation [i] would yield OA(1684, 86, S16, 80), but

(6, 6+85, 151)-Net in Base 16 — Upper bound on s
There is no (6, 91, 152)-net in base 16, because
