I need a method to aggregate in order to retrieve the existence of
two or more rows that have equal values in selected columns.

In this example (i.e aggregate on column1, 2 and 3), I want to
retrieve row no. 1 and 3.

c1 c2 c3 ... cN
1 3 5 ...
1 3 7 ...
1 3 5 ...
2 3 7 ...


Is it possible to do this in Excel - without specifying predefined
criteria values?

Thanks for any suggestions
