July 23, 1983 Here is page 21 of Cunningham Table additions. Part of page 22 is shown below. Davis and Holdridge factored three more "wanted" numbers. I finished the C51's. I am doing the C52's now. Dick Lehmer and Bob Silverman noticed that #535 on page 20 was wrong. The factor of 2,1106M should read 2454574823653. I am processing the first update to the Cunningham Table now. It will go in a pocket in the back of the book when it is published. It will list factors #320 to #565. That's why there is a line after #565. My new addresses are enclosed. Keep the factors coming!
