(257−173, 257, 121)-Net in Base 2 — Upper bound on s
There is no (84, 257, 122)-net in base 2, because
- 20 times m-reduction [i] would yield (84, 237, 122)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2237, 122, S2, 2, 153), but
- the (dual) Plotkin bound for OOAs shows that M ≥ 21 202164 777340 611954 999570 008915 022189 929806 762507 427497 459274 415511 437312 / 77 > 2237 [i]
- extracting embedded OOA [i] would yield OOA(2237, 122, S2, 2, 153), but
