(97, 97+94, 213)-Net over F2 — Upper bound on s (digital)
There is no digital (97, 191, 214)-net over F2, because
- extracting embedded orthogonal array [i] would yield linear OA(2191, 214, F2, 94) (dual of [214, 23, 95]-code), but
- residual code [i] would yield OA(297, 119, S2, 47), but
- 1 times truncation [i] would yield OA(296, 118, S2, 46), but
- the linear programming bound shows that M ≥ 3649 328393 569529 653896 227896 426496 / 35409 > 296 [i]
- 1 times truncation [i] would yield OA(296, 118, S2, 46), but
- residual code [i] would yield OA(297, 119, S2, 47), but
(97, 97+94, 243)-Net in Base 2 — Upper bound on s
There is no (97, 191, 244)-net in base 2, because
- the generalized Rao bound for nets shows that 2m ≥ 3286 345835 685558 350605 490942 186974 822130 251388 005033 010828 > 2191 [i]
