[next] ~~~ [up] Subject: cube group theory.

In one of the previous letters on the subject of cubing
there was a letter from some one offering to put together a piece
on group theory and cubing, I for one would certainly be interested in
seeing it. When I took my cube apart and tried to put it together
I wondered as to how many ways there are of putting it together
so that the cube is unsolvable, i.e. how many equivalence classes
are there which are 'wrong'.
Any one worked it out, I would but group theory is unfortunately not
my strongest subject.
