Could you please shortly explain your above message, e.g. "One would expect that if you have n languages, there are n*(n-1) possible routes of mapping." What do you mean by "language", "route", "mapping"
As I think , the google translate is useful if you translate words alone but if you you need translate sentences then it is not useful. So most languages on google.
Then the question is of HOW does PC translate, say from Latin to Greek if the teacher was absent? Any popular models of it? Maybe PC uses connections like Latin->English then English->Greek? Are there these connections REALLY in google computer or not? Google engineers said it?
