Claim:
A method comprising: associating, by a computer-based system for compression, one or more of a plurality of unique entities with one or more of a plurality of unique binary numbers, wherein a unique binary number corresponds to a base 10 value of the form 2 (n−1) , and wherein the associating further comprises associating, by the computer-based system, a most frequently occurring entity with a binary number corresponding to a base 10 value of 2 0 , and associating, by the computer-based system and based upon a frequency of occurrence, less frequently occurring entities with binary numbers corresponding to increasing powers of the number two; associating, by the computer-based system, a collection with the plurality of unique entities; and determining, by the computer-based system, that the collection includes one of the plurality of unique entities based upon the unique binary number associated with the unique entity.
