Here, we make available downloadable Mathematica notebooks whose commands are copied from the Latex files of the monograph by Roger Chalkley titled 

The Research about Invariants of Ordinary Differential Equatons.

They are evaluated for the purpose of showing that all of the Mathematica input statements in the manuscripts are free of misprints and produce the indicated output.   They may also be useful for other purposes.
