Macaulay is available from zariski.harvard.edu (128.103.1.107) via anonymous FTP I am not certain how much support they will provide, but I note the program has been around and improved over the last 5 years or so at least. Macaulay is designed to handle the kinds of computations which arise in algebraic geometry, commutative ring theory, homological algebra, and the like. It is an excellent, efficient implementation of Groebner-basis routines. Typical applications involve finitely-presented modules or ideals over polynomial rings over a finite field; one may obtain presentations for kernels, syzygies, resolutions, and so on. Macaulay takes a couple of meg including the manual, so one ought to think twice before requesting the file. But given any real reason to use these capabilities, I think you should run right out and get it. Source code (in C) is provided, and I understand it can be compiled on a Mac. I also have an old version which fits in a PC (even an XT). Dave Rusin (rusin@math.niu.edu)
