You are supposed to decode the list of numbers with a Base 18 or Base 20 number system, the same used on the Mesoamerican Long Count calendar mentioned in the Hint about a Hint.

So far, I have been unsuccessful. I believe that it may be encoded in Base 18 (the first letter in the list of names also correspond to the same) and then further encoded in Base 3 or incorporates it. As previously mentioned, The number of names in the list total to 18 when you add Frank's name.

So far, I have been using the Base64 and Binascii libraries in Python 3.3 to try encoding and decoding all of these. There is an online converter that takes numbers and converts them to different base-N configurations as well.
