(156−100, 156, 234)-Net over F3 — Upper bound on s (digital)
There is no digital (56, 156, 235)-net over F3, because
- 1 times m-reduction [i] would yield digital (56, 155, 235)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3155, 235, F3, 99) (dual of [235, 80, 100]-code), but
- residual code [i] would yield OA(356, 135, S3, 33), but

(156−100, 156, 253)-Net in Base 3 — Upper bound on s
There is no (56, 156, 254)-net in base 3, because
