The content of M of n codes was merged into Constant-weight code on February 7, 2011. The former page's history now serves to provide attribution for that content in the latter page, and it must not be deleted as long as the latter page exists. For the discussion at that location, see its talk page.

I suggest merging balanced code into constant-weight code. While balanced codes are one of the most important kinds of constant-weight codes, there seems to be a lot of overlap in these articles -- most of the properties of balanced codes are also true of all other constant-weight codes. --DavidCary (talk) 05:33, 28 April 2012 (UTC)Reply

• Support. You are right. It seems that balanced codes are just special constant-weight codes where w = n/2. If you could merge the article properly that would be great. Nageh (talk) 11:43, 4 May 2012 (UTC)Reply

I know the number of codewords in an m of n code is ${\displaystyle {\tbinom {n}{m}}={\tfrac {n!}{m!(n-m)!}}}$, but I don't want to add it to the section without a reference. Any suggestions?—Theodore Kloba (☎) 18:52, 20 October 2017 (UTC)Reply
