(84, 233, 372)-Net over F3 — Upper bound on s (digital)
There is no digital (84, 233, 373)-net over F3, because
- 2 times m-reduction [i] would yield digital (84, 231, 373)-net over F3, but
- extracting embedded orthogonal array [i] would yield linear OA(3231, 373, F3, 147) (dual of [373, 142, 148]-code), but
- residual code [i] would yield linear OA(384, 225, F3, 49) (dual of [225, 141, 50]-code), but
- 1 times truncation [i] would yield linear OA(383, 224, F3, 48) (dual of [224, 141, 49]-code), but

(84, 233, 375)-Net in Base 3 — Upper bound on s
There is no (84, 233, 376)-net in base 3, because
- 1 times m-reduction [i] would yield (84, 232, 376)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 530 832722 876684 135527 794554 380622 940706 594698 665075 369067 506417 698033 733257 019724 990478 809762 988142 076597 410769 > 3232 [i]
