Have an even number of circles completely contained inside of other circles. Clockwise from top left: 0,2,2,2,2,2.

• Good spot, but there is a confusion on the right side, bottom right, the only diagram where gur pbagnvarq pvepyrf vagrefrpg. – Weather Vane Oct 7 '18 at 19:11
• There’s no confusion there — on the right side, exactly two circles are completely contained inside the larger circle. The intersection is not a circle itself, and a circle intersecting with another is not fully contained inside the other circle. – El-Guest Oct 7 '18 at 20:51
• I am talking about bottom right. Which are you replying about? – Weather Vane Oct 7 '18 at 20:54
• The bottom right corner of the right side. How many circles would you count as fully contained? @WeatherVane – El-Guest Oct 7 '18 at 20:56
• The same but I don't get your comment about that area: "a circle intersecting with another is not fully contained inside the other circle". They are both fully contained. My point is that they intersect, unlike any other contained circle. – Weather Vane Oct 7 '18 at 20:58
