\{n,m\}
\{n,\}
\{n\} 

Matches the single character regular expression or subexpression immediately
preceding it at least n and at most m times.  If m is omitted, then it
matches at least n times.  If the comma is also omitted, then it matches
exactly n times.

n is the typical metasyntactic variable for indicating some arbitrary
number. It makes sense to use it here. Then, 'at most m times'. Thus, think
most, think m.

Or it could just be that m is right to the right of n on a qwerty
keyboard...
