Soma cube their faces, such that at least one inside corner is formed. There is one combination of three cubes that satisfies this condition, and six combinations of four cubes that satisfy this condition, of which two are mirror images of each other (see Chirality). Thus, 3 + (6 × 4) is 27, which is exactly the number of cells in a 3×3×3 cube. The Soma cube was analyzed in detail by John Horton Conway on September 1958 in Mathematical Games column in "Scientific American", and the book "Winning Ways for your Mathematical Plays" also contains a detailed analysis of the Soma
