Binary B2-Sequences: A New Upper Bound

G. érard Cohen, Simon Litsyn, Gilles Zémor

Research output: Contribution to journalArticlepeer-review


We show that the maximum size of a B2-sequence of binary n-vectors for large enough n is at most 20.5753n, thus improving on the previous bound 20.6n due to B. Lindström.
