Alright I'll bite on this... just to remind of what's going on...
Consider this "random" sequence:
Is it random? How random is it? One way to proceed is to transform the sequence into something shorter. Define this "alphabet"
A = 00
B = 01
C = 10
D = 11
... And then rewrite the sequence using these letters, replacing pairs of two digits:
Now, the thing should be easier to analyze. Either proceed by eyeball, or proceed by defining yet another alphabet and repeating the previous idea. Either way, I can rewrite the sequence as:
Showing lots of order now. In fact, now someone can see I just copied the string ABCDBCD three times, meaning the original sequence is three copies of: 00011011011011
Anyway, that's how this kind of problem is cracked. It can be generalized like crazy. http://barnes.x10host.com/pages/Binary-A...er-One.php
