Contribution from Johannes W. Meijer (meijgia(AT)hotmail.com), Feb 20 2009: (Start)
a(n) = 20a(n-1)-175*a(n-2)+882*a(n-3)-2835*a(n-4)+6072*a(n-5)-8777*a(n-6)+8458*a(n-7)-5204*a(n-8)+1848*a(n-9)-288*a(n-10)
a(n) = -(105/2)-(143/3)*n-14*n^2-(4/3)*n^3+756*2^n+48*2^n*n^2+384*2^n*n-(3645/2)*3^n-405*3^n*n+1120*4^n
G.f.: (1+38*z-108*z^2-242*z^3+839*z^4-444*z^5-180*z^6)/((1-z)^4*(1-2*z)^3*(1-3*z)^2*(1-4*z))
