The obvious pattern now is that every 8 bytes there is a repeated sequence of 6 bits which are all the same. Despite my initial protestations that the latter part of the file is less regular, this pattern holds throughout the entire file. The majority of the time the pattern is 111111, but there are a decent number of ones which are 000000 as well.
Okay, here’s something interesting. Showing binary representation, in blocks of 8 bytes:
