Figure 1.31: Hexagram: (a) Magic Hexagram. (b) Star of David. (c) Chinese<br />

Checkers<br />

A hexagram is a six-pointed star, with a regular hexagon at its center,<br />

formed by combining two equilateral triangles (Figure 1.31). Throughout the<br />

ages and across cultures, it has been one of the most potent symbols used in<br />

magic [49]. The yantra of Vishnu, the Supreme God of the Vishnavite tradition<br />

of Hinduism, contains such a hexagram [193]. Mathematically, a normal magic<br />

hexgram (Figure 1.31(a)) arranges the first 12 positive integers at the vertices<br />

and intersections in such a way that the four numbers on each line sum to the<br />

magic constant M = 26 [87, p. 145]. This can be generalized to a normal<br />

magic star which is an n-pointed star with an arrangement of the consecutive<br />

integers 1 thru 2n summing to a magic number of M = 4n + 2 [308].<br />

The Star of David (Figure 1.31(b)) is today generally recognized as a symbol<br />

of Jewish identity. It is identified with the Shield of David in Kabbalah,<br />

the school of thought associated with the mystical aspect of Rabbinic Judaism.<br />

Named after King David of ancient Israel, it first became associated with the<br />

Jews in the 17th Century when the Jewish quarter of Vienna was formally<br />

distinguished from the rest of the city by a boundary stone having a hexagram<br />

on one side and a cross on the other. After the Dreyfus affair in 19th Century<br />

France, it became internationally associated with the Zionist movement. With<br />

the establishment of the State of Israel in 1948, the Star of David became<br />

emblazoned on the Flag of Israel [278].<br />

Figure 1.31(c) contains the playing board for the inappropriately named<br />

Chinese Checkers. The game was invented not in ancient China but in Germany<br />

by Ravensburger in 1893 under the name “Stern-Halma” as a variation<br />

of the older American game of Halma. “Stern” is German for star and refers<br />

to the star-shaped board in contrast to the square board of Halma. In the<br />

United States, J. Pressman & Co. marketed the game as “Hop Ching Checkers”<br />

in 1928 but quickly changed the name to “Chinese Checkers” as it gained<br />

popularity. This was subsequently introduced to China by the Japanese [236].
