Comment: to Combination puzzle, which despite its name has a link to the Tower Cube at "2x2x3" in the table. Based on comparable articles this is a clear preserve rather than a delete, and is appropriate for |in-article listing. Most of the data on these items, such as David Singmaster's ''Cubic Circular'' periodical, was written in the 80s and is not available online
