(248−183, 248, 82)-Net in Base 2 — Upper bound on s
There is no (65, 248, 83)-net in base 2, because
- 6 times m-reduction [i] would yield (65, 242, 83)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2242, 83, S2, 3, 177), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 735 008378 947807 881106 651760 309054 102584 233301 100257 486578 588179 737729 826816 / 89 > 2242 [i]
- extracting embedded OOA [i] would yield OOA(2242, 83, S2, 3, 177), but
