Only three, I believe.

 

This is the minimal amount.

 

So in the center, there is a 7-ball pattern in both...

 

 O O

O O O

 O O

 

Looks like that

 

So we have for the first one

 

O O O O

  O O O

    O O

      O

And if we take away those at 10, 2, and 6 o'clock we have

 

 O O

O O O

 O O

 

and if we add the OOOs

 

we have

   O

 O O

O O O

 O O

 

     O

   O O

 O O O

O O O

 

     O

   O O

 O O O

O O O O

 

Wonderful!

 

So that's the smallest I can thinjk of.
