Thanks for sharing your experience.  I was asking because I did not
seem to be successful in getting anything from web-searching.

Yes; I was intrigued by the paper.

Good question.

| International Symposium, DISCO '93, Gmunden, Austria,
| September 15-17, 1993 : proceedings
| (Lecture notes in computer science)
| You might want to check if your library has a copy.

Thanks, I'll try that.

| Gauss: A Parameterized Domain of Computation System with
| Support for Signature Functions, by M.B Monagan, page 81.
