%N List of coefficients of chromatic polynomial of icosahedron, highest order terms first.

%D N. Biggs, Algebraic Graph Theory, 2nd ed. Cambridge University Press, 1993. See p. 69.

%e The polynomial is x^12 - 30*x^11 + 415*x^10 - 3500*x^9 + 20023*x^8 - 81622*x^7 + 241605*x^6 - 517360*x^5 + 780286*x^4 - 782108*x^3 + 463310*x^2 - 121020*x.
