How can I loop over N objects using 3 objects each iteration

Question

Hello

 

Let's suppose I have 4 objects, and I want loop over these objects using a function involving 3 objects in each call as follows:

 

1. MyFunction(object1, object2 , object3);
2. MyFunction(object1, object2 , object4);
3. ...
4. MyFunction(object2, object1 , object3);
5. MyFunction(object2, object1 , object4);
6. ...
7. MyFunction(object4, object2 , object1);
8. MyFunction(object4, object2 , object3) ;

 

 What is the general algorithm for this ?

 

Thanks at advance
