32bits (8bit letter) - COMPRESSION - 21bits (binary code).

Encoding a 4 letters text (simulation in Excel) using fewer bits in EXCEL.

Working with data compression algorithms that allows reconstructed the original 4 letters word data from the compressed data (3 letters word).

I don't use a statistical model for the input data... I use bit sequences and a strong algorithms.

The ZIP4LETTERS can be used like a cryptosystem. The ZIP4LETTERS consists of a pair of algorithms, one for encryption/compression and other one for decryption/decompression.
