Proof (by ttt2 @ termCOMP 2023)

1 Rule Removal

Using the Knuth Bendix order with w0 = 1 and the following precedence and weight functions
prec(.) = 0 weight(.) = 0
all of the following rules can be deleted.
.(.(x,y),z) .(x,.(y,z)) (1)

1.1 R is empty

There are no rules in the TRS. Hence, it is terminating.
