An Elongated Pentagonal Orthocupolarotunda
(one of the 92 Johnson solids) has 37 faces, 15 of which are squares, 7 of which are regular pentagons, and 15 of which are triangles.
How many vertices does it have?
(In reply to solution
Each edge is shared by two faces. So there are only 70 edges. So there are only 35 vertices.
