Mistake

There is only one way in which consecutive integers can be fitted into a magic hexagonal array ... The numbers $1$ to $19$ can be so arranged, a fact first discovered by T. Vickers.

Correction

While T. Vickers did actually publish a result in $1958$, he was not the first to discover it.

Many have discovered it independently, from as far back as Ernst von Haselberg in $1897$.

In David Wells: Curious and Interesting Numbers (2nd ed.), this statement has been removed.
