(94, 193, 198)-Net over F2 — Upper bound on s (digital)
There is no digital (94, 193, 199)-net over F2, because
- 3 times m-reduction [i] would yield digital (94, 190, 199)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2190, 199, F2, 96) (dual of [199, 9, 97]-code), but
- residual code [i] would yield linear OA(294, 102, F2, 48) (dual of [102, 8, 49]-code), but
- residual code [i] would yield linear OA(246, 53, F2, 24) (dual of [53, 7, 25]-code), but
- 1 times code embedding in larger space [i] would yield linear OA(247, 54, F2, 24) (dual of [54, 7, 25]-code), but
- adding a parity check bit [i] would yield linear OA(248, 55, F2, 25) (dual of [55, 7, 26]-code), but
- “vT4†bound on codes from Brouwer’s database [i]
- adding a parity check bit [i] would yield linear OA(248, 55, F2, 25) (dual of [55, 7, 26]-code), but
- 1 times code embedding in larger space [i] would yield linear OA(247, 54, F2, 24) (dual of [54, 7, 25]-code), but

(94, 193, 223)-Net in Base 2 — Upper bound on s
There is no (94, 193, 224)-net in base 2, because
- 1 times m-reduction [i] would yield (94, 192, 224)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 6969 116650 168480 435527 754883 821814 729999 094261 825406 742730 > 2192 [i]
