Caesar Cypher & The Substitutions have been on tour, and as tradition dictates, the souvenir tour T-shirt bears a list of the cities visited on the back. But of course, since we're talking about one of Europe's leading cryptographic jazz combos, the list is in code:

080476
410488
631428083607
735616461
440401478
235476731
540631
616431
461546410

The list contains no information apart from the city names. Can you work out their itinerary?

(In reply to re: Number hints by Charlie)

Difficulty?  I'd assume that one wouldn't last long with RSA or CIA this was a barrier.  Though I had concepts of 'splitting' the triplets, nothing came to me.

Jenny, great puzzle.

The CIA/RSA is obiously not passed in here lightly.  I note that Phil Zimmerman in his development of PGP may well have used mod and bases in his development or 128 encryption.

As I understand it, a secure site sends me a couple of keys to which I respond with my 'public' one.  Ths is translated and enables encrypted transfer between server and client, in both directions.
