Raanan's computers produced 7th known AP24:

1630799846252777 + 985151*23#*n, for n=0 to 23

It sets no record (although it has the largest known start).

Unfortunately, we have almost used up the best search area suitable

for my program and we will have to move to progressions with larger

start, where primes are less frequent :-(

Below is summary of all known AP24 sorted by progression difference.

After each progression I have given start and end divided by 10^15:

515486946529943 + 136831*23#*n, for n=0 to 23, 0.515487 - 1.21759
