If equal value in list says true or false syntax.

I want to make a cull pattern and keep the faces that do not face itself. For that, I try to use a syntax that says ‘per value’ if it as a similar companion in the ‘whole list.’ With that, I can get a ‘true and false list’ to dispatch the double faces.

I tried ‘set’ and others. But somehow, I cannot find the component that creates a list of true’s and false’s on similarities in the list. Is there a component for that.
