Termination Proof Script

Consider the TRS R consisting of the rewrite rule
1:    f(f(a,x),a)  → f(f(f(x,a),f(a,a)),a)
There are 4 dependency pairs:
2:    F(f(a,x),a)  → F(f(f(x,a),f(a,a)),a)
3:    F(f(a,x),a)  → F(f(x,a),f(a,a))
4:    F(f(a,x),a)  → F(x,a)
5:    F(f(a,x),a)  → F(a,a)
The approximated dependency graph contains one SCC: {2,4}.
