Hadi Kharaghani and Behruz Tayfeh-Rezaie announced on 21 June 2004 that they constructed a Hadamard matrix of order 428. As a result, the smallest order for which no Hadamard matrix is presently known is 668.

You can actually download a text file of their matrix and verify it yourself, so what's the problem? Ntsimp 17:11, 12 September 2006 (UTC)

[edit] Hadamard matrices of order 764 exist
