Henry Ernest Dudeney/Modern Puzzles/196 - Les Quadrilles

 * Les Quadrilles
 * This old French puzzle will, I think, be found very interesting.


 * It is required to arrange a complete set of $28$ dominoes so as to form the figure shown in the diagram,
 * with all the numbers forming a series of squares.


 * Thus, in the upper two rows we have a square of blanks, and a square of four $3$'s, and a square of $4$'s, and a square of $1$'s and so on.

 * This is, in fact, a perfect solution under the conditions usually imposed,
 * but what I now ask for is an arrangement with no blanks anywhere on the outer edge.
 * At present every number from blank to $6$ inclusive will be found somewhere on the margin.
 * Can you construct an arrangement with all the blanks inside?
