I have been reviewing issues of the "CUBIC CIRCULAR" ,a set of which I recently
obatined form Singmaster, and would like references to information on the
1- a book Rubik edited called "A BUVOS KOCKA" which was to be also done in
english by PENGUIN.
2 - Rubik's newsletter "RUBIK'S - LOGIC AND FANTASY DIMENSIONS"
3- "TEN BILLION BARREL" puzzle invented by Gumpei Yokoi. Possibly a reference
to a published?? solution by Trevor Hutton. This is supposed to be harder than
the cube and is available for about $6 at Child World in northen NJ.
4 - "TRILLION" a flat version of 3.
