Puzzles and Curious Problems by Henry Ernest Dudeney: $282$
- The Magic Hexagon
- In the diagram it will be seen how the numbers from $1$ to $19$ are arranged so that all $12$ lines add up to $23$.
- Six of the lines are the six sides, and the other six lines radiate from the centre.
- Can you find a different arrangement that will still add up to $23$ in all the $12$ directions?
