Abstract

What really made everything tick in Chapter 11 was Lemma 11.4:

$$2m/2 \times (Pm + Qm \times \sqrt {3} ) = (1 + \sqrt {3} )m$$

. Unfortunately, few continued fraction expansions satisfy such a nice relationship. It was Lucas’ idea to concentrate on those sequences that do whether or not they arise from a continued fraction expansion.

“The Mathematicians are a sort of Frenchmen: when you talk to them, they immediately translate it into their own language, and right away it is something utterly different.”

- Johann Wolfgang Von Goethe
