From New Scientist #1455, 9th May 1985 [link]
The team of seven has remained unchanged since 1981. The Chancellor described the annual team photographs to me as follows:
1981: Fred, Graham, Hermann, Jack; and men from Trinity, Unity and Varsity.
1982: Ken, Fred, Graham; and men from Unity, Varsity, Westminster and Sanctity.
1983: Graham, Hermann, Jack, Ken; and men from Varsity, Sanctity and Trinity.
1984: Jack, Ken, Fred; and men from Westminster, Unity, Trinity and Sanctity.
“Can you match up the names and colleges?”
“Surely”, I said, “there is some duplication, isn’t there?”
“Yes. There are three men of the same name. But there are not three men from one college”.
I found I still couldn’t do a complete matching, but I could say with certainty that ______ college had two men in the team.
Which college, and which two names?
