- Reflected F
- Rotated F
- A regular polygon with n sides has n reflection lines that meet at the center. If n is even, there are lines that go from each corner to its opposite corner, and each side to its opposite side. If n is odd, all lines go from a corner through the midpoint of the opposite side.
- C3 or C6 if you ignore the black border diamonds - note the crossed arms destroy any mirror symmetry.
- None. Details of arms destroy the mirror symmetry.

- a. D3; b. D1; c. None; d. D1; e. C3; f. D5
- C2 symmetry is strongly suggested. A 180° rotation interchanges the devil and Jesus. Also, horizontal and vertical reflections change the figures with the goats. Jesus was a scapegoat - a symbol of blame for the problems of his society. Escher suggests the Devil was instrumental in his scapegoating.
- C4. Overlaps prevent D4. The center portion has C8 or even C16 depending on how much you ignore.
- C4. Preserving colors reduces to C2.
- C2 is strongly suggested, though not precisely present.
- C3 is strongly suggested.
- C2 symmetry interchanging colors. No color preserving symmetry.
- There is a suggestion of a color interchanging D1 symmetry. But the two sides are not quite the same.
- Draw C2-C6, D2-D6 with a motif.
- Two rotation centers
- This poem can be read normally, or by reading each column of words downwards.
