 OFFSET 0,2 COMMENTS Exponents are prime numbers in decreasing order. LINKS Ivan Panchenko, Table of n, a(n) for n = 0..1000 FORMULA a(n) = n^5 + n^3 + n^2. G.f.: x*(3 + 26*x + 60*x^2 + 30*x^3 + x^4)/(1-x)^6. - R. J. Mathar, Nov 14 2007 EXAMPLE a(7)=17199 because 7^5 = 16807, 7^3 = 343, 7^2 = 49 and we can write 16807 + 343 + 49 = 17199.
