## Question:Too long an ODE?

Maple

I have an ODE to solve that looks like this:

((diff(R(r), r, r, r, r))*r^4+3*(diff(R(r), r))*r-3*(diff(R(r), r, r))*r^2+2*(diff(R(r), r, r, r))*r^3-3*R(r)+4*R(r)*n+2*R(r)*n^2-4*(diff(R(r), r))*r*n+2*(diff(R(r), r))*r*n^2+4*(diff(R(r), r, r))*r^2*n-2*(diff(R(r), r, r))*r^2*n^2-4*R(r)*n^3+R(r)*n^4)/r^4 = (-108-1362*n+2122*n^2+2019*n^3-3032*n^4+401*n^7+1192*n^6-1033*n^5-25*n^9+6*n^10-180*n^8-4128*r^(n+3)*n^3+2304*r^(n+3)*n-576*r^(n+5)*n-760*n^6*r+575*n^5*r-244*n^7*r-2108*n^3*r-11616*r^(n+3)*n^4-5280*r^(n+3)*n^5-456*n^2*r-6912*r^(3*n+3)*n^3+192*r^(n+3)*n^7-6*n^10*r+152*n^8*r+13*n^9*r-192*r^(n+5)*n^7+4224*r^(3*n+3)*n^2-9216*r^(3*n+3)*n^5-16512*r^(3*n+3)*n^4-1632*r^(n+5)*n^6-1536*r^(3*n+3)*n^6-7680*r^(n+5)*n^3-8832*r^(n+5)*n^4-3360*r^(n+5)*n^2-96*r^(n+3)*n^6+2304*r^(3*n+3)*n-5376*r^(n+5)*n^5+2546*n^4*r+4800*r^(n+3)*n^2)/(576*r^4+192*r^4*n^4+1248*r^4*n^3+2688*r^4*n^2+2208*r^4*n)

Maple returned a result containing integrals that remained to be solved. I had a very similar ODE with fewer terms, which Maple was able to solve without returning any integrals. Is this a memory ot algorithm issue? I would like Maple to solve my ODE fully as it stands now without breaking the ODE into parts. Can anyone shed light on this? Thank you.
