Alexander´s Star - Invented by
Adam Alexander in 1982
The Alexander's Star is in used condition, one orange
sticker is missing. Please see the photo.
The design of the puzzle practically forces the stickers
to peel on the corners. Measures 3 1/4 inches sypherical.
This is an odd puzzle to solve, and never really looks
complete unless you know what you're looking for. The
puzzle is solved when each pair of parallel planes is
made up of only one colour. To see a plane, however,
you have to look "past" the five pieces on
top of it, all of which could/should have different
colours than the plane you're solving.
Alexander's Star is a mechanical puzzle invented by
Adam Alexander in 1982. This puzzle is in the shape
of a great dodecahedron, which is one of the Kepler-Poinsot
polyhedra. As a puzzle it has 12 vertices which are
the axes of rotation. There are 30 moving pieces which
have two colours each. Each piece forms the edge between
two vertices, and five such edges join at each vertex.
The great dodecahedron has 12 pentagonal faces, but
as these go through the interior of the solid, only
part of each pentagon is visible from the outside. The
visible part of a pentagon consists of a ring of five
triangles. Each ring must be all of one colour, and
rings on opposite sides of the puzzle must be the same
colour.

This puzzle is equivalent to just the edges of the
megaminx. There is however one minor difficulty with
the star because only six colours are used and therefore
each colour combination occurs twice. It is not terribly
difficult to solve, but this puzzle is infamously hard
to twist. It was invented by Adam Alexander, a US mathematician,
who patented it on 26 March 1985, US
