Group. A group is a finite or infinite set of elements together with a binary operation (called the group operation) that together satisfy the four fundamental properties of closure, associativity, the identity property, and the inverse property. basic example of a finite group is the symmetric group, which is the group of permutations (or under permutation) of objects. The simplest infinite group is the set of integers under usual addition. For continuous groups, one can consider the real numbers or the set of invertible matrices.
