I posted a question that, in retrospect, was too broad, and it received two votes to close with comments telling me why. I edited it to substantially restrict its scope, and it was upvoted and answered on February 13th. Then today it was closed with the reason "This question needs to be more focused." Why is it considered unfocused in its current form?

The question: Can you explain how to convert this notation to a function to someone unfamiliar with group theory?

The paper referenced in the question: "On $C^2$-smooth Surfaces of Constant Width" by Brendan Guilfoyle and Wilhelm Klingenberg

    $\begingroup$ For future reference, the canonical way to request reopening etc. is this thread or a more current version of it (generally replaced year to year). $\endgroup$
