bilateral symmetry

Let V = R^k be a k-dimensional vector space over R, let S subset V, and let W = {w element V:w·n^^ = 0} be a subspace of V of dimension k - 1, where n^^ is a unit normal vector of W. Then S is said to have mirror symmetry about W if S contains the vector s_1 = s - 2n^^(s·n^^) whenever it contains s. The vector s_1 is the mirror image of s about W.
