R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(x, f(f(a, a), a)) -> F(f(a, f(a, a)), x)
F(x, f(f(a, a), a)) -> F(a, f(a, a))
Furthermore, R contains one SCC.

↳Remaining Obligation(s)
The following remains to be proven:
Dependency Pairs:
F(x, f(f(a, a), a)) -> F(a, f(a, a))
F(x, f(f(a, a), a)) -> F(f(a, f(a, a)), x)
Rule:
f(x, f(f(a, a), a)) -> f(f(a, f(a, a)), x)
