(6, 6+30, 93)-Net over F7 — Upper bound on s (digital)
There is no digital (6, 36, 94)-net over F7, because
- extracting embedded orthogonal array [i] would yield linear OA(736, 94, F7, 30) (dual of [94, 58, 31]-code), but
- construction Y1 [i] would yield
- linear OA(735, 45, F7, 30) (dual of [45, 10, 31]-code), but
- construction Y1 [i] would yield
