Abstract: The present invention proposes an algorithm that can be further compressed even if it has already been compressed by any compression method. When 26 kinds of binary clusters are expressed in ascending length order and the rank of each order is index, a value of (length of the binary cluster + index)/2 is called average, and if the average is not an integer, it is rounded up to the length of a final compressed binary cluster. For example, the average of a 32-bit binary cluster corresponding to index 23 is 27.5, so it is rounded to 28, so the 32-bit binary cluster can be compressed by 4 bits to 28 bits.
