Naturally Ordered Semigroup Exists

Theorem
There exists a Naturally Ordered Semigroup.

Proof
We take as axiomatic the Zermelo-Fraenkel axioms.

From these, Existence of Minimal Infinite Successor Set is demonstrated.

This proves the existence of a minimal infinite successor set.

Then we have that the Minimal Infinite Successor Set Fulfils Peano Axioms.

It follows that the existence of a Peano structure depends upon the existence of such a minimal infinite successor set.

Then we have that a Naturally Ordered Semigroup Satisfies Peano's Axioms.

Hence the result.
