Hi,
Can you post the details of the linear algebra? How big was the matrix? What was its density? How long did it take to solve? etc. Bob

Here are some details from Richard about the linear algebra:
We collected about 46.1 million relations. After filtering these were reduced to a matrix with dimensions 2387874 x 2390123. The matrix weight was 91470168. Total time to solve the matrix on one CPU of Richard's G5 PowerMac was 824595 seconds (about 9.5 days). Don Leclair
