FORMULA
G.f.: -(6684*x^4-2956*x^3+489*x^2-36*x+1)/((6*x-1)*(7*x-1)*(8*x-1)*(9*x-1)*(10*x-1)). [Colin Barker, Aug 12 2012]
From Elmo R. Oliveira, Sep 12 2024: (Start)
E.g.f.: exp(6*x)*(exp(4*x) - exp(3*x) - exp(2*x) - exp(x) + 3).
a(n) = 40*a(n-1) - 635*a(n-2) + 5000*a(n-3) - 19524*a(n-4) + 30240*a(n-5) for n > 4. (End)
