Above:Solved
The above is currently the only image for this item.
A cross between an Octagonal Prism and a Cube. A 3x3x3 truncated on 2 edges. The result has a shape resembling a house.
This puzzle is part of the series "Octgonal Edges". All modifications of this series are made by truncating an 3x3x3 on its edges. These truncations are symmetric as in the mass produced octagon from which the series takes its name.
The technical signature (Octagonal Edges 294) indicates where to cut the original cube.
Without the keyword "Extended" it is a variant made only by truncating the original cube. With the word "Extended" some sides left over from the original receive additional extensions to "delete" some of these remaining faces.
This variant is a very old member of the series because it can be made just by swapping some pieces between an octagon an a cube.
The museum knows two extended version of this puzzle.
This puzzle was shown in the book "Puzzles Old and New How to Make and Solve Them" which was published in 1986. This gives an upper bound for this puzzles publication.
