Abstract: For each prime power $ p^m$, we realize the classical cyclotomic polynomial $ \Phi_{p^m}(x)$ as one of a collection of $ 3^m$ different polynomials in $ \mathbf{Z}[x]$. We show that the new polynomials are similar to $ \Phi_{p^m}(x)$ in many ways, including that their discriminants all have the form $ \pm p^c$. We show also that the new polynomials are more complicated than $ \Phi_{p^m}(x)$ in other ways, including that their complex roots are generally fractal in appearance.
