(100−90, 100, 978)-Net over F27 — Upper bound on s (digital)
There is no digital (10, 100, 979)-net over F27, because
- 18 times m-reduction [i] would yield digital (10, 82, 979)-net over F27, but
- extracting embedded orthogonal array [i] would yield linear OA(2782, 979, F27, 72) (dual of [979, 897, 73]-code), but

(100−90, 100, 981)-Net in Base 27 — Upper bound on s
There is no (10, 100, 982)-net in base 27, because
- 16 times m-reduction [i] would yield (10, 84, 982)-net in base 27, but
