Talk:Fractal string

List of lengths
The list $$\{\ell_1,\ell_2,\ldots\}$$ seems to use set notation, but the example $$\{\frac{1}{3},\frac{1}{9},\frac{1}{9},\ldots\}$$ includes a repetition $$\ell_2=\ell_3$$ in the list. The source "Riemann Zeroes and Phase Transitions via the Spectral Operator on Fractal Strings" uses curly braces but describes the lengths as forming a sequence, in which case would it be more appropriate to use a sequence of lengths?
