Line 12: == Symmetrization == {{main\|Symmetrization}} Given any function f in ''n'' variables, ~~<math>f(x_1,\dots,x_n)~~with values in an abelian group,~~</math>~~ it can be made into a symmetric function by averaging over permutations. Similarly, it can be made into an anti-symmetric function by averaging over [[even permutation]]s and subtracting the average over [[odd permutation]]s. == Applications ==
