Deletion of Flat 4D Rubik puzzle

Comment: for those voting "Merge":  What exactly should be merged?  It has already been established that the particular, individual subject "Flat 4D Rubik puzzle" fails  due to the complete lack of reliable secondary sources covering it, and that the general topic already has a good article at n-dimensional sequential move puzzle.  So, what should be copied out of this article and into n-dimensional sequential move puzzle?  100% of the content of this article is copied from the non-notable web page of the puzzle http://puzzlemystery.com/FlatRubikPuzzle.aspx?r=10 here, and copied self-promotionally by the author of that web page, I note--all the pictures being copied in from that web page are tagged as copyright-released by the author.  The puzzlemystery page relates only to that particular non-notable varietal of the general n-dimensional sequential move puzzle.  If by "merge" we mean "Add a link to http://puzzlemystery.com/FlatRubikPuzzle.aspx?r=10 under External Links at n-dimensional sequential move puzzle, I agree, but "merge" should not retain any more content from this article than that
