Between 400 and as many as 600 distinct Indus symbols have been found on seals, small tablets, ceramic pots and more than a dozen other materials, including a "signboard" that apparently once hung over the gate of the inner citadel of the Indus city of Dholavira.
Ten Indus Signs, dubbed Dholavira Signboard
Typical Indus inscriptions are no more than four or five characters in length, most of which are tiny; the longest on a single surface, which is less than 1 inch (2.54 cm) square, is 17 signs long; the longest on any object (found on three different faces of a mass-produced object) has a length of 26 symbols.
In a 2009 study by P. N. Rao et al. published in Science, computer scientists, comparing the pattern of symbols to various linguistic scripts and non-linguistic systems, including DNA and a computer programming language, found that the Indus script's pattern is closer to that of spoken words.
The messages on the seals are too short to be decoded by a computer.
