permutation

[pur-myoo-tey-shuhn]

noun:

an arrangement of a set of elements

Explanation

A permutation is one of the possible ways to arrange things belonging to a given set. It's a concept used in math, logic, and language alike, wherever order matters and variations multiply. Every shuffled deck, revised sentence, or changed itinerary could be seen as a fresh permutation of what's possible.

Example: We tried every possible permutation of the letters to crack the code.
