In mathematics, a nonempty subset S of a group G is said to be symmetric if it contains the inverses of all of its elements. (Wikipedia).
Symmetric Groups (Abstract Algebra)
Symmetric groups are some of the most essential types of finite groups. A symmetric group is the group of permutations on a set. The group of permutations on a set of n-elements is denoted S_n. Symmetric groups capture the history of abstract algebra, provide a wide range of examples in

What is the Symmetric Difference of 2 Sets?
What is the symmetric difference of 2 sets? In this video we go over the symmetric difference of sets, explaining it in a couple ways including what is probably the briefest way. The symmetric difference of two sets A and B is (A union B)-(A intersect B). If you need to know what the defin

Introduction to sets || Set theory Overview - Part 1
A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other #sets. The #set with no element is the empty

Equal Symmetric Difference Implies Set Equality | Set Theory
If the symmetric difference of A and B is equal to the symmetric difference of A and C, then B and C must be equal! We prove this basic set theory result about symmetric differences in today's lesson. Of course, the converse is true trivially. If B=C then any operation between A and B is t
