Is it appropriate to use two "of"s in quick succession?

For example in this phrase:

Creation of library of gas turbine components in MATLAB/SIMULINK

Is there a better way of phrasing this?

Note: Substituting "creation" with "creating" is not desirable here

Edit for more context: The phrase is the title for my diploma thesis

    You are missing an article: "Creation of a library...". For software libraries you can use "for" instead of "of" if it's used to mean a codebase and not a collection of data. You can then rephrase the title as "Creation of a library for gas turbine components in MATLAB/SIMULINK" or "Creation of a gas turbine component library in MATLAB/SIMULINK"

    As @dubious points out, for is a better preposition than of for the second context. But that just means it's a poor example context. And as a general rule, there's absolutely nothing "unusual", "incorrect", or "awkward" about sequences like the son of the sister of..., so it's misleading to suggest that it should be rephrased for the sake of "style" Commented Nov 10, 2021 at 16:12
  • The preposition "to" also may be used multiple times in a sentence, e.g., "I gave the book to Tom to give to his sister to study." Two "to's" in infinitives, two "to's" as prepositions. If I were writing, I'd try to phrase it differently, but we often spek a bit repetitiously. BTW, there are even tutus, in ballet. Commented Nov 11, 2021 at 0:41

Even if it's grammatically acceptable to repeat words, nevertheless you might make the decision to avoid it for aesthetic reasons.

In the following examples, () represents optional words, while slashes such as "of/for" are "alternatives".

On a CV or resume, you could write:

Created gas turbine components library/libraries in MATLAB/SIMULINK

If a title of a school paper:

(New) MATLAB/SIMULINK gas turbine components library/libraries

A (new) library of/for gas turbine components, created in MATLAB/SIMULINK

A (new) MATLAB/SIMULINK library of/for gas turbine components
