Palais\"" I forgot to tell you that I am keeping all of the programs for my book on the computer in my office at Maryland so that they are available via ftp. Do an anonymous log in: ftp bianchi.umd.edu There are two subdirectories of pub. One contains the latest versions of the programs CSPROGS.m, SURFS.m, CURVES2D.m and CURVES3D.m The other subdirectory contains Mathematica Notebooks.
