## THE CROSS OF CARDS.

(

Problems Concerning Games.)

In this case we use only nine cards--the ace to nine of diamonds. The

puzzle is to arrange them in the form of a cross, exactly in the way

shown in the illustration, so that the pips in the vertical bar and in

the horizontal bar add up alike. In the example given it will be found

that both directions add up 23. What I want to know is, how many

different ways are there of rearranging the cards in order to bring

about this result? It will be seen that, without affecting the solution,

we may exchange the 5 with the 6, the 5 with the 7, the 8 with the 3,

and so on. Also we may make the horizontal and the vertical bars change

places. But such obvious manipulations as these are not to be regarded

as different solutions. They are all mere variations of one fundamental

solution. Now, how many of these fundamentally different solutions are

there? The pips need not, of course, always add up 23.
