Abstract: Systems and techniques are disclosed to express sequences of codes, and in particular sequences of ASCII characters, in a lossless compressed format. The techniques may include dividing a universe of expressible codes into smaller subsets, called code sets, such that every code exists within one code set, but no code exists within two code sets. The code sets are then utilized for compression based on the heuristic that it is more likely that a next code in the sequences of codes is in the same code set as a previous code in the sequences of codes, rather than that the next code in sequences of codes being in any other code set (sentence structure).
