Fermilab Calls For Code Crackers

atrocious cowpat passes along a call for help from symmetry magazine, the joint publication of Fermilab and SLAC, noting: "Could be just plain gibberish, it could be something like those wonderfully weird letters to the Mount Wilson observatory, or it could be a message from aliens who just happened to have gotten their hands (tentacles/exoskeleton) on a fax machine." "A little over a year ago, the Fermilab Office of Public Affairs received a curious letter in code (4.4-MB image here). It has been sitting in our files all that time and we haven't had much of a chance to look into breaking the code, nor are we particularly expert at this!"

      I independently transcribed the same as you, so I confirm the same digits. Also, assuming the first blob is ternary (I=0, II=1, III=2), the second is hex, and the last is binary, I get the following numbers in decimal:
      ternary = 720113244210716512990341782103795379056660114385796527
      hexadecimal = 74506518313470710988407084006

      Of course, this assumes also that these are supposed to be read left-to-right, top-to-bottom, and that the most significant digits come first. Can anyone else confirm these values?

    All ovals are ellipses... Incorrect. All ellipses are ovals, but not the other way around (sic).

    So a round is an oval but an oval is not a round.

    (trying to move the interesting stuff to the top) The top and bottom part of the code code the same data. The little indentation at the beginning of the line is important and means that the previous line continues. The indentation in the bottom bottom part is of, perhaps because of writing conditions.

    It's true:
    remove the linebreaks from the first block, interpret # of lines as trinary digits 0,1,2 (|->0, ||->1, |||->2) and you get
