The occurence of Number 52 (and 26) is too frequent within Genesis posts to be just random. We haven't figured out the meaning of it, but here are some observations.
Genesis messages started in 1997. 1+9+9+7 = 26.
Also, the page numbers facing left total 52.
52 is two times the number of letters of the alphabet.
52 is the number of weeks in a year.
Craig McGee posted some observation of number 52 in his "Leap of Faith" thread on the publiusenigma forum.
13, 26 and 52 could be linked to ROT13 cypher.
