The latest CCRL Rating Lists and Statistics are available for viewing from the following links:

http://www.computerchess.org.uk/ccrl/404FRC/ (FRC 40/4)

Please note that the three lists are often updated separately to each other. The FRC list is only updated when a new engine or engine version is being/has been tested.
Also, please note that the 40/40 and 40/4 lists are totally different databases and not comparable to each other.
