This puzzle is part of the series "Octagonal 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 A528A00145294) 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.
The extended version is Greenhills Octahedron.

The "Million Space Shuttle" (a derivate of this puzzle) was first mentioned in David Singmasters Cubic Circular Issue 1 from Autumn 1981.
Edge length: 56 mm
Weight: 84 grams
