Hello,
I found the Lie symmetry package symmgrp.max and after uppercase'ing
it and the *.dat files, it worked with maxima-5.5 with gcl. Maxima5.6
would only build under clisp on hpux10.20. So I tried running the
the test cases. All worked OK except the largest (s_kar1.com).
After taking long time, it crashed with saying that it
could not take CAR of LAMBDA. I checked that both clisp and gcl does
not take CAR of ATOMs. I think there may still be something wrong with
the CLISP Maxima. Maybe related to memory since smaller examples work
OK. Anyway, once the cvs on sourceforge is up we can put the
symmgrp.max there since it is working with gcl. There are pretty good
docs/papers that come with the package.
