It was the night before the Berlin Wall went up, and Maria was trying to signal the United Kingdom.. She kept sending the same message to Nigel, who forgot that she often sent messages using cyrpto-arthmetic. Her message was
After spending all night worrying, Nigel remembered her emergency signal was to send a cryptographic message 3 times in a row. The answer would be the time to rendezvous at the train station for her extraction. It was 08:00 and Nigel hoped that N = 1, otherwise he would not make it in time to save her
There are at least two correct solutions - one time that is at least 2 hours before the 2nd time. Maria was clever enough to send a signal with a backup time in case Nigel was late.
