How many times does a number appear in these lines?

Hi

someone could help me find a function that checks in loop if an i and j number of each line appears in the other lines more than 2 times?

%Connecting points i --> j: Edge(k,:) = [i, j];

Edge = [1 2;

2 3;

3 4;

2 6;

3 7;

5 6;

6 7;

7 8];

i corresponds to the left number an j to the right one.

Thank you!
