Here's a very fast prime number calculater made by the Project Gutemberg guys. You probably know them; they put out thousands of eTexts. This program was used by them to calculate the first hundred thousand prime numbers. Also included are the Think C++ documents and source code. The source code in C is availible separately for IBM and UNIX compilers who can't run the mac application.
Qs, Comments, hate mail (especially), direct it all to EVetere.
