In the mathematics subfield of abstract algebra, group theory studies algebraic structures called (symmetry) groups.

Groups recur throughout mathematics and various physical systems

(e.g., the hydrogen atom, crystals, public key cryptography, and three of the four known fundamental forces in the universe)

can be mathematically modeled by symmetry groups.
