About SRBase
is a mathematical research project that uses Internet-connected computers trying to solve Sierpinski / Riesel Bases up to 1030. Prove the conjectures by finding at least one prime for all lower values of k.The project is in collaboration with the Mersenne CRUS project.
The server is running on a private computer in a VM.
