6-bit Binary Compression is a fast compression routine based on a 4-byte data word translation via 6-bit bit parity table . 6 bit table entries were computed by ommitting last two bits (having decimal values 1 and 2) in a single byte (0 to 255) giving 64 index entries combination (s) per data byte . Also all truncation entries from a 4-byte data word have only 256 combination (s) . The 4 6-bit (truncated) dictionary entries are (re) indexed and writen to a compressed data output file in a truncated index number order having (binary) length (s) from 7 to 18 bits compared to the original data 32 bit (word) length . Useful for compressing large document data files (binary and text data documents) . Yet compression gain in ASCII data files is obvious due to short binary length of index number entries .
