 OFFSET 0,3 COMMENTS Exponents are the prime numbers in decreasing order. LINKS G. C. Greubel, Table of n, a(n) for n = 0..1000 FORMULA a(n) = n^5 + n^3 - n^2. G.f.: x*(1 + 30*x + 60*x^2 + 26*x^3 + 3*x^4)/(1-x)^6. - R. J. Mathar, Nov 14 2007 EXAMPLE a(7)=17101 because 7^5=16807, 7^3=343, 7^2=49 and we can write 16807+343-49=17101.
