(118−100, 118, 275)-Net over F8 — Upper bound on s (digital)
There is no digital (18, 118, 276)-net over F8, because
- extracting embedded orthogonal array [i] would yield linear OA(8118, 276, F8, 100) (dual of [276, 158, 101]-code), but
- construction Y1 [i] would yield
- OA(8117, 140, S8, 100), but

(118−100, 118, 295)-Net in Base 8 — Upper bound on s
There is no (18, 118, 296)-net in base 8, because
- 2 times m-reduction [i] would yield (18, 116, 296)-net in base 8, but
- extracting embedded orthogonal array [i] would yield OA(8116, 296, S8, 98), but
