| In 1895, William Radcliffe discovered, after much trial and error, that nineteen hexagonal pieces numbered from one to nineteen can be assembled so that each row of three, four or five hexagons adds up to tthirty-eight. In 1963, Charles Trigg proved that it is the only magic hexagon of any size! | ||
