Combinatorics
Combinatorics is the branch of mathematics studying theenumeration,combination, andpermutation ofsets of elements and the mathematical relations that characterize their properties.
Mathematicians sometimes use the term "combinatorics" to refer to a larger subset ofdiscrete mathematics that includesgraph theory. In that case, what is commonly called combinatorics is then referred to as "enumeration."
The Season 1 episode "Noisy Edge" (2005) of the television crime dramaNUMB3RS mentions combinatorics.
