From what I've read, in 1975, Jacques Sesiano in his Ph.D. thesis managed to translate four 'new' books from Diophantus' Arithmetica. This brings the total number of books of Arithmetica salvaged to 10 distinct books, if we include the 6 from Heath's Greek translation.


Does anyone know if any of the 6 Greek version of the books were found in Arabic? Has there been other major progress in finding the last 3 books?



Other Arabic translations of the Arithmetica
As Sesiano writes in his book, the first three books that once existed in Arabic translation (by Qusta ibn Luqa) are lost. But al-Karaji quoted extensively from Diophantus Book III (and gives almost all of Book IV)
in his work *Fahri*, which proves that the Books I-III must have been known
in Arabic times. 


The situation has not changed since the publication of the Arabic books by Rashed and Sesiano: Rashed and Houzel do not mention any new discoveries in their book *Les Arithmétiques de Diophante* from 2013.
