It is listed as the 51 knot in the Alexander-Briggs notation, and can also be described as the (5,2)-torus knot. The cinquefoil is the closed version of the double overhand knot. The cinquefoil is a prime knot. Its writhe is 5, and it is invertible but not amphichiral. Its Alexander polynomial is :$\backslash Delta(t)\; =\; t^2\; -\; t\; +\; 1\; -\; t^\; +\; t^$, its Conway polynomial is :$\backslash nabla(z)\; =\; z^4\; +\; 3z^2\; +\; 1$, and its Jones polynomial is :$V(q)\; =\; q^\; +\; q^\; -\; q^\; +\; q^\; -\; q^.$ These are the same as the Alexander, Conway, and Jones polynomials of the knot 10132. However, the Kauffman polynomial can be used to distinguish between these two knots. The name “cinquefoil” comes from the five-petaled flowers of plants in the genus ''Potentilla''. ==See also== *Pentagram *Trefoil knot *7₁ knot *Skein relation 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cinquefoil knot」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
