• found: CRC concise encyclopedia of mathematics, c2003:p. 2923 (Symmetry: an intrinsic property of a mathematical object which causes it to remain invariant under certain classes of transformations (such as rotation, reflection, inversions, or more abstract operations). The mathematical study of symmetry is systematized and formalized in the extremely powerful and beautiful area of mathematics called group theory.)

• found: Encyclopaedia of mathematics, v. 9, c1993:p.102 (Symmetry: an involutory orthogonal transformation that changes the orientation (an involutory transformation is a transformation that, when applied twice, yields the identity.)
• found: Wikipedia.org, Feb. 16, 2006(Symmetry in mathematics occurs not only in geometry, but also in other branches of mathematics. It is actually the same as invariance: the property that something does not change under a set of transformations. A function of n variables may be invariant under certain permutations of the variables. These permutations form a group, a symmetry group ... One studies the symmetry of a given object by collecting all the operations that leave the object unchanged. These operations form a group. For a geometrical object, this is known as its symmetry group; for an algebraic object, one uses the term automorphism group.)
