Put a letter on each face of an icosahedron such that a five-letter word can be read clockwise around each vertex. Specifically, these words:
ENDOW ERODE LANES NAMED RESTS ROLLS SEEMS SEWER SLOTS SMALL STORE WORSE
Every word in the above list will appear around exactly one vertex.
Some letters might appear on multiple faces.
As an illustration of how it might look, notice how the word ENDOW can be read clockwise around the vertex:
If you don't have a 3-D model of an icosahedron to work on, you might consider printing out the planar graph of an icosahedron. Just keep in mind that the 20th face stands outside the graph.
