SUMMARY
A field of order p² exists for every prime p, as established through the construction of monic quadratics in Zp[x]. The Frobenius endomorphism plays a crucial role in this proof, confirming the existence of such fields. The discussion highlights the importance of understanding polynomial rings and their properties in finite fields.
