(99, 99+91, 238)-Net over F2 — Upper bound on s (digital)
There is no digital (99, 190, 239)-net over F2, because
- 1 times m-reduction [i] would yield digital (99, 189, 239)-net over F2, but
- extracting embedded orthogonal array [i] would yield linear OA(2189, 239, F2, 90) (dual of [239, 50, 91]-code), but
- residual code [i] would yield OA(299, 148, S2, 45), but
- 1 times truncation [i] would yield OA(298, 147, S2, 44), but
- the linear programming bound shows that M ≥ 386 271048 917458 443577 540946 323578 953396 125696 / 1194 549431 128209 > 298 [i]
- 1 times truncation [i] would yield OA(298, 147, S2, 44), but
- residual code [i] would yield OA(299, 148, S2, 45), but
- extracting embedded orthogonal array [i] would yield linear OA(2189, 239, F2, 90) (dual of [239, 50, 91]-code), but
(99, 99+91, 262)-Net in Base 2 — Upper bound on s
There is no (99, 190, 263)-net in base 2, because
- 1 times m-reduction [i] would yield (99, 189, 263)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 822 616674 061834 532576 288971 464014 397716 147335 065252 288128 > 2189 [i]
