Among them, to the amphicheiral projections of 41 (22) and 63 (2122) correspond even polynomials [46]. |
Liang polynomial A(t) [28] is defined by the similar determinant, where aii = te, and aij = s if the vertices i, j are connected with the multiplicity s (s = 0,1,2). In this case, for the amphicheiral knot projections A(t) = A(t -1). For example, for the amphicheiral knot 41 (22) we have A(t) = A(t -1) = -4t2+8t-3+8t -1-4t -2. |
