We consider a particular geometric action on a family of exact Lagrangian fillings of Legendrian (2, n) torus links. We give a brief geometric description and then describe the induced action on a Floer-theoretic invariant known as the augmentation variety. An identity studied by Euler in the context of continued fractions makes a surprise appearance.
