We use the reduction pair processor [13].

The following pairs can be strictly oriented and are deleted.

PRIME1₂(x, s₁(s₁(y))) -> PRIME1₂(x, s₁(y))

The remaining pairs can at least by weakly be oriented.
none
Used ordering: Combined order from the following AFS and order.
PRIME1₂(x1, x2) = PRIME1₁(x2)
s₁(x1) = s₁(x1)

Lexicographic Path Order [19].
Precedence:

s₁ > PRIME1₁

The following usable rules [14] were oriented: none
