This figure:
can be made from two of the seven SOMA-pieces.Which ones? And how?
(If you start with the above figure of two SOMA-pieces it is particularly difficult to build the cube.)
. . . And with all 7 SOMA-pieces many hundredshapes can be built.
SOMA looks so easy.But even with a few SOMA-pieces difficult shapes
can be made.

SOMA for expertsBuy SOMA for your children - but don't let them get holdof it!
Humphrey H. Welder,
If the smallest of the SOMA-pieces, No. 1, is re-

It looks easy!

First build these two regular figures:
using respectively 3 and 4 of the 7 SOMA-pieces.
These two figures can then be put together inthree different ways to form the cube.
There is a special way of building the cube.

Some geniuses are very poor at Somaand some morons seem specially gifted with thekind of spatial imagination that Soma exercises.Everyone who takes such a test wants to keep play-ing with the pieces after the test is over.
The number of pleasing structures that can bebuilt with the seven Soma pieces seems to be un-limited. When I wrote the column about Soma inScientific American, I supposed that few readerswould go to the trouble of actually making a set. I

The charm of Soma derives in part, I think, fromthe fact that only seven pieces are used; one is notoverwhelmed by complexity.

The same result was arrived at by N. S. Newhallof the trajectory department at the Jet PropulsionLaboratory of the California Institute of Technology,Pasadena, California, using an IBM 7094 electroniccomputer which printed out the solutions in 82seconds. The result has later been verified byseveral other scientists.
- one million, one hundred and five thousand, ninehundred and twenty – different ways (counting asdifferent all solutions which are reflections of eachother or that can arise from each other by rotationsof the whole cube or of single pieces).
This figure is based on the result of an analysisby Dr. John H. Conway and Dr. M. J. T. Guy, both ofCaius College, Cambridge, England, carried out bymeans of an electronic computer.
