Signature

FilledSmallSquare Signature[list] gives the signature of the permutation needed to place the elements of list in canonical order.

FilledSmallSquare Examples: Signature[a,b,c] LongRightArrow; Signature[a,c,b] LongRightArrow.

FilledSmallSquare The signature of the permutation is , where is the number of transpositions of pairs of elements that must be composed to build up the permutation.

FilledSmallSquare If any two elements of list are the same, Signature[list] gives 0.

FilledSmallSquare See Section 3.2.5 and Section 3.7.11.
