Pages 49 to 51 and 256 Byte Strings

Pages 49 to 51 contain the alpha-numeric string given at the bottom of this post.
In the string there are 256 pairs. The first character of each pair is always a 0,1,2,3 or 4, and the second is one of 59 (prime) unique characters, the digits 0 to 9, 26 upper case letters and 23 lower case letters:

    0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,a,b,c,d,e,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x

Another Skipped f

It’s interesting to note that 'f' has been skipped, something similar is found when solving the earlier pages (in the pages that have a decryption key each letter f in the message is not encrypted, f is used as an interrupter, pages that are just encoded do not skip 'f').

Interpreting The String

One way to interpret this string is that it is a representation of numbers in Base64, Base 60, Base 59, or something else?

Typical Base64 encoding  starts with capital letters, then lower case letters, then numbers:

    A = 0, B = 1, C = 2, …     a = 26, b = 27, c = 28 …     0 = 52, 1 = 53, 2 = 54 …

After some discussion on solvers we decided to try the Base 59 mapping of characters to numbers. We chose to start with the numbers, then the 26 Upper case letters and then the 23 lower case letters, giving this map from each possible base 59 pair to decimal. There are other choices but this seems reasonable (and gives us an interesting result).

A 256 Byte String

Using the Base 59 assumption we get a decimal number for each pair.  All the decimal numbers are in the range 0 to 255, an unsigned 8 bit (1 byte) number, (“unsigned char” in c). What makes this more interesting is that in the 2014 we found three 256 byte numbers that were never used:

Four 256 Byte Strings

We now have four 256 byte strings. At first glance the 4 strings look random, perhaps they can be combined in someway, or they are encrypted, or they are a key or a passphrase that will help us make progress?

I am not completely sure which one is correct so I am posting both version of 4th string:

<crashdemons> I think that's the right one
<crashdemons> for base59 and base61 conversions
<crashdemons> base62 was fail: one of the "bytes" had a value over FF
<crashdemons> for anyone interested in reproducing it, Radix-N (arbitary) to base 10 (decimal) is done by sum( Vn*B^Pn ) for n=0 to the word length across the Base-B digits where B is the base, Vn is the decimal digit value (position in the alphabet of the Base), and Pn is the 0-based position in the 'word'
<crashdemons> so Pos('3')*59^1 + Pos('N')*59^0 etc
<crashdemons> *n=1 to the word length or n=0 to length-1 (correction)
