FORMULA

E.g.f. exp(1-(1-6*x)^(1/6))-1.

D-finite with recurrence: a(n) +15*(-2*n+7)*a(n-1) +5*(72*n^2-576*n+1169)*a(n-2) -45*(2*n9)*(24*n^2-216*n+497)*a(n-3) +20*(324*n^4-6480*n^3+48735*n^2-163350*n+205877)*a(n-4) -12*(6*n-35)*(6*n-31)*(3*n-16)*(2*n-11)*(3*n-17)*a(n-5) -a(n-6)=0. - R. J. Mathar, Jan 28 2020
