The list { ℓ 1 , ℓ 2 , … } {\displaystyle \{\ell _{1},\ell _{2},\ldots \}} seems to use set notation, but the example { 1 3 , 1 9 , 1 9 , … } {\displaystyle \{{\frac {1}{3}},{\frac {1}{9}},{\frac {1}{9}},\ldots \}} includes a repetition ℓ 2 = ℓ 3 {\displaystyle \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?
