(102−87, 102, 1327)-Net over F25 — Upper bound on s (digital)
There is no digital (15, 102, 1328)-net over F25, because
- 1 times m-reduction [i] would yield digital (15, 101, 1328)-net over F25, but
- extracting embedded orthogonal array [i] would yield linear OA(25101, 1328, F25, 86) (dual of [1328, 1227, 87]-code), but
