No?

I would guess that the “odd” depends very much on one’s background and nature. I would bet that a painter or artist in general, would reply with no hesitation bottom left, since it is the only “ugly” one. Mathematical interpretation of “ugly” :the only one without an axis of symmetry. Symmetry is important! More important than concavity. ðŸ™‚

The biggest challenge is to find a reason each one of the 4 things doesn’t belong.
Some sample reasons for the cover shapes
* Top Left: Is a regular hexagon.
* Top right: Is concave. All others are convex. Also, can be divided into 3 squares. Every angle is a right angle.
* Bottom Left: Every side is a different length
* Bottom Right: Has 5 sides/is a pentagon. All others have 6.
