In an icosahedral die, the sum of the numbers on opposite vertices is equal to 13. Symmetry is applied to the die to move some vertices into the original vertices, as shown in the table, which specifies images of the other vertices.


Choose the type of symmetry and click "new example" to generate a puzzle.
