(248−186, 248, 79)-Net in Base 2 — Upper bound on s
There is no (62, 248, 80)-net in base 2, because
- 17 times m-reduction [i] would yield (62, 231, 80)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2231, 80, S2, 3, 169), but
- the LP bound with quadratic polynomials shows that M ≥ 980047 981244 260057 815735 332443 337614 248057 474048 194890 833078 439779 500032 / 255 > 2231 [i]
- extracting embedded OOA [i] would yield OOA(2231, 80, S2, 3, 169), but
