Construction of the Polybius Square

The construction of the Polybius Square involves creating a 5×5 grid layout typically filled with letters of the alphabet, omitting ‘J’ which is often combined with ‘I’. The method starts by arranging the letters in rows and columns, ensuring no repetition within the square.

Subsequently, numerical values are assigned to the letters based on their positions in the grid. For example, in the first row, ‘A’ could be represented by 11, ‘B’ by 12, and so forth. This systematic assignment of numbers to letters establishes the foundation for encoding and decoding messages using the Polybius Square cipher.

This process of constructing the Polybius Square provides a unique and structured framework for encrypting and decrypting messages.
