Figures made of 24 Bar Magnets

Contents of this web page

Introduction top
When AlnicoMagnets appeared years ago, I bought two
sets of 12 bar magnets enough to build two cubes.
The bar magnets were one of my grandchildren's favourite
toy at each age. Now they are getting older and I asked some of them (8,
10, 13 years old) to build figures for my homepage. Conditions were, the
figures must be symmetric and all 24 bar magnets must be used. They did
it with much enthusiasm. I show their figures on this page as 3D
pictures. so they are better to be recognized.

the 3D view.

What a pity. One ball is missing. But two cubes have
16 balls.
Here is the hexagon star made of 24 bar magnets.

Cuboctahedron
...... 
If you fold the triangles downwards and form rightangled
triangles with the outer bar magnets, a famous Archimedean solid arise,
the cuboctahedron. 
This is the pair.
Now you have the question, whether there
are more figures with 24 edges known by names. I found five ones.
Gyroelongated
square bipyramid (Johnson 17)
Triangular
orthobicupola (Johnson 27)
Truncated
tetrahedron with three face diagonals
Octagon

Hexagonal
