The Lost Symbol cover has these two number sequences:
"22-65-22-97-27"
"22-23-44-1-133-97-65-44"
which can be decoded (using substitution) to "POPES PANTHEON" perhaps referring to the Jefferson Memorial which was designed by John Russell Pope, but more likely refers to the House of the Temple, Home of The Supreme Council, 33°, Ancient & Accepted Scottish Rite of Freemasonry, Southern Jurisdiction.
UPDATE: It appears that a gentleman named Billy Gates notified (or was working in conjunction with) with the
Secrets of the Lost Symbol blog on August 26 at 4:22 p.m. even though they didn't
publish the find until Sunday September 13. I'm glad that there is now confirmation of this find and that it appears to be on the right track... to what is still anyone's guess. At least one other gentleman named "Ted" came up with the same independently, his comment is at the
Cryptex.
UPDATE 2: Whereas, There are people, including myself, that were working on this code
before the book was released; and whereas, Billy Gates has also tried explaining the same to the commenters
here; and whereas, Most people working on these codes presumed they were page or chapter numbers and could therefore use mono/poly-alphabetic substitution; and whereas, The book having been published, we can all see
now that the numbers refer to chapters; and whereas, We all know that this is the same strategy Dan Brown used in
Digital Fortress; and Whereas, People have called my cell phone to personally tell me that I'm "making this all too complicated" and such; NOW, BE IT THEREFORE Resolved, that any post published before September 15, 2009 is most likely referring to efforts to decode clues on the cover without physically having the book.
