+\begin{abstract}
+This is the remaining ODEs of the Kamke test suite as published by 
+E. S. Cheb-Terrab\cite{1}. They have been rewritten using Axiom
+syntax. Where possible we show that the particular solution actually
+satisfies the original ordinary differential equation.
+
+Note that after a certain point Axiom can no longer generate useful
+results. The failures fall into several cases which have been included
+in other regression test files.
