Dear all,

GAP - http://www.gap-system.org

I am writing a Java program which I have to throw a set of GAP
commands for GAP to compute some group permutations, as GAP do not
have a Java API, can anyone give me some hints how can I achieve that?

The program will able to throw data to GAP, let GAP compute, and then
send the data back to my program and then display the result on my
program's GUI

Thanks

Hi, rndgroup-ga:

Would you like for me to post an elaboration on the Java to GAP
"connector" approach suggested below?

regards, mathtalk-ga

Sure thanks

Have you seen this?

Looks like it does what you need.

JavaMath has stopped development.
I need GAP's approach

thanks

Since the GAP package is command-line oriented, you may find that the
only practical approach is (some variation on) open a "shell" process
and work with the output as redirected to a file.

I suppose the weak point of this approach is in parsing the results
into semantically useful structures.  The OpenMath project, which is
at least tangentially connected with the JavaMath link posted by
vladimir-ga, is still active.

A Java to GAP "connector" can be downloaded from the Research
Institute for Applications of Computer Algebra:
