# The 100 dollar bill puzzle

Hi, my friend gave me a puzzle, and I need help in solving it. I am required to decrypt this code and get a password. Please help! The hint is: $100 bill. Here's the text version of the image above: A,M,L, ,F,M,A,A N,L, ,C,F,H,E,G L,U, ,E, ,E,T, H,W,I,I,S, ,L,T F,N,O,T,H,E,C,E ,N,R,O,M,O, ,E , ,E,A, ,N,T,T M,T, ,R,E,T,T,E  • Can we assume USD$100? Does it matter which version of the bill we reference? Does it matter that some of the letters are indented with spaces or is that in error? Oct 27, 2015 at 14:41
• Are you sure that spacing is correct? Some of them look off.

• @JoeZ. I did my best to match the image but, given that it's an image, I can't be positive. I'd like OP to weigh in if the spacing even matters. Oct 27, 2015 at 16:04

So it was reading Dan Brown's The Lost Symbol that got me the answer to this one, along with that one deleted answer that mentioned "Benjamin Franklin" (because his face appears on the US \$100 bill).

The key is to use the "order eight Franklin square" mentioned in that book, and map each letter of the grid to that position. Specifically, this one (from this site):

If we do that, we get:

TELL WON THE NAME GF THE ELEMENT TTHAT COMES AFTER CALIFORNIUM

Which I assume was supposed to read:

TELL NOW THE NAME OF THE ELEMENT THAT COMES AFTER CALIFORNIUM

Which is, of course, einsteinium.

• @squeamishossifrage That message starts with "SAGHEIS" and is only 63 letters long, so I assume you missed a space somewhere.
