## Mistake

*$F_{n + 1} = F_0 F_1 F_2 \ldots F_{n - 1} + 2$, from which it follows ...*

## Correction

That expression should be:

- $F_n = F_0 F_1 F_2 \ldots F_{n - 1} + 2$

This statement (and indeed, the entire paragraph it is in) has been removed from *Curious and Interesting Numbers, 2nd ed.* of $1997$.
