It is surprising to see that name of one person who has solved a core mathematics problem recently appears more than once in the side view. Even my name appeared in some of the views of sets which I had not touched even.
Moreover I would like to draw Calvin's attention here. Some sets are having problems which only differ in some of the values. It is very uneasy if you can't solve a problem of that type and when you hope to see a new problem you find the same problem with some changed data.
