From the developer:
PolyFactors factors univariate polynomials over the integers.
PolyFactors uses the ZZX polynomial type and the ZZXFactoring routines from Victor Shoup's NTL (http://www.shoup.net/ntl/). He deserves most of the credit. PolyFactors just provides a GUI for input and output.
PolyFactors is a Universal Cocoa application.
