As, may be, most of the books and personal ideas.

But i have found it quoted by Anand V. Raman a computer scientist
at Massey University in New Zealand in an article about "The
Katapayadi Formula and the Modern Hashing Technique"; an also
quoted by B. van Nooten, University of Califonia, in an article about
"Binary Numbers In Indian Antiquity", and again quoted by
Subhash Kak, Lousiana University in the introduction of a book
"Computing Science in Ancient India" were also are included the two
articles before mentioned.

Well i mention this because it makes me have some confidence in
the book of Georges Ifrah. But, even if there are mistakes in the
book i think it is worthy reading it because its understability
and the treatiment of a subject of a similar neccesity as the origin
of the alphabets that unoften is posible to find.
No doubt, allways would be nice to find more and better.

Yours,
