"The Greek historian and cryptographer Polybius is credited
with a significant advance in signaling and ciphermaking.
Based on an idea developed by the philosopher Democritus,
the Democritus/Polybius system used various torch signals
to represent letters of the Greek alphabet. In the history of
cryptography, Polybius is immortalized for his creation of a
true alphabet-based system based on a five-by-five grid
configuration, which came to be known as a Polybius checker-
board. This system was the first to provide a transferral of letters
to numbers in a pattern that was relatively easy to recall, and
became a foundation of later cryptographic techniques."

Clandestine Communicatons. Fred B. Wrixon

system was learned about 10+ years after the
discovery of this same idea and exploration of
its cryptographic possibilities for the record.]

[compare to the LED alphanumeric displays
and the HIOX model which is a 5x5 model,
of the letters and alphabet in a visual form,
which could be used for cryptography and
also for performing mathematical functions
via calculating relations between structures,
for example genetic sequences in which the
letters are part of a computational model.]
