If called upon to choose between moves A and B, the machine consulted this total, played A if the num- ber was even, B if odd. When he pinched two adjacent triangles together and pushed the op- posite corner of the hexagon toward the center, the hexagon would open out again, like a budding flower, and show a completely new face.

Moore, both at that time on the staff of Bell Telephone Laboratories.

Hexaflexagons and Other Mathematical Diversions by Martin Gardner

On this latter view, the pro- posed solution is inadequate, but even in terms of strictly formal lying, it is faulty because of its ambiguity. The resulting table will always possess the magic property of forcing a diverskons by the procedure de- scribed, and this number will always be the sum of the two sets of numbers that generate the table.

The procedure makes it impossible, of course, for the five selected cards to include duplicates.

The first player is sure to win if he immediately occupies mathematicao one of the four cells numbered in Figure The booklet revealed the secret of forming a knot in a cloth band without resorting to magical trickery.


Therefore the first player can win. This was the only money Hamilton ever re- ceived directly, his biographer tells us, for a discovery or publication. Lay a penny on this number and elim- inate all the other numbers in the same row and in the same column by covering them with markers. This pattern is encountered frequently in mathematical puzzles.

Figure 6 shows how a geometrical hexaflexagoons may be drawn on one face so as to appear in three different configurations. In experimenting with higher-order Hexagons, a handy rule to bear in mind is that the sum of the number of leaves FIG. It will then contain the same number of reversed cards as there are reversed cards in the group of 32 held by the spectator.

Hexaflexagons and Other Mathematical Diversions

It would find the mark not on the floor but on the ceiling, and it would require a second trip around the bands to find it on Curious Topological Models 65 the floor again! I was just along for the ride, and it was pleasantly diverting at that. On a 3 x 3×3 cube the first player has an easy win. Like the Moebius strip covering, this surface appears to be two separate surfaces, one otherr the other.

In this case the chosen numbers must be multiplied instead of added. Tuck- erman senior devised a simple but efficient tree diagram for the theory. The simple or honest liar an- swers “yes” and sets off for the village.

America’s Greatest Puzzlist 89 and pal are on squares mathematcal another color. Use all 12 matches the entire length of each match must be used to form in similar fashion the perimeter of a polygon with an area of exactly four square 7.


The third form, folded from the overlapping figure-8 strip, is the first of what Louis Tuckerman calls the “street flexagons.

When the game is played on a two-by-two board four hexa- gonsthe player who makes the first move obviously wins. When I was a sophomore in high school inI remember going to the library once and seeing a magazine I had not noticed before— the Scientific American.

The number of hexagons may vary, but the board usually has 11 on each edge.

Adam Atkinson rated it really liked it Sep 28, Let us con- sider surfaces with no more than two edges, and edges that are either simple closed curves or in the form of an ordinary single knot. On the remaining plays, make the only transfer possible that does not involve the smallest disk. Tuckerman, who was formerly with the National Bureau of Standards. By omnibus I traveled to Hexaflexgons.

In short, I offer to double the penalty with each toss and I continue until I am obliged to pay off. So cleverly and scientifically do they Sam Loyd: He can do this easily by making six cuts through the cube, keeping mathematkcal pieces together in the cube shape [see Fig.
