(175−113, 175, 247)-Net over F3 — Upper bound on s (digital)
There is no digital (62, 175, 248)-net over F3, because
- 2 times m-reduction [i] would yield digital (62, 173, 248)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3173, 248, F3, 111) (dual of [248, 75, 112]-code), but
- residual code [i] would yield OA(362, 136, S3, 37), but

(175−113, 175, 277)-Net in Base 3 — Upper bound on s
There is no (62, 175, 278)-net in base 3, because
- 1 times m-reduction [i] would yield (62, 174, 278)-net in base 3, but
