Yeah, the definition of the Erdos Discrepancy Problem is borked. See the abstract http://arxiv.org/abs/1402.2184 for a correct definition. Oh heck, I'll go fix it in a second. --75.145.68.89 (talk) 06:38, 18 February 2014 (UTC)[reply]

OK, much cleaned up. The EDP section now reads like valid math, and properly describes and references the new proof. --75.145.68.89 (talk) 07:18, 18 February 2014 (UTC)[reply]

Barker sequences only have low autocorrelation (±1) when they are not aligned. When they are aligned (offset =0 they have autocorrelation equal to the sequence length, i.e. 11 or 13.86.166.175.123 (talk)
