EXAMPLE

The chromatic polynomial is x^20 - 30*x^19 + 435*x^18 - 4060*x^17 + 27393*x^16 - 142194*x^15 + 589875*x^14 - 2004600*x^13 + 5673571*x^12 - 13518806*x^11 + 27292965*x^10 - 46805540*x^9 + 68090965*x^8 - 83530946*x^7 + 85371335*x^6 - 71159652*x^5 + 46655060*x^4 - 22594964*x^3 + 7171160*x^2 - 1111968*x.
