  It appears to be the same person asking both questions. Vassil, are you attempting to reopen your previous version of this question, or is this supposed to be a new variation that's distinct from the previous one?

  @JeffSchaller - definitely not a variation, it's the same (identical) self-answered question, by the same person.

  @JeffSchaller Yes, I'm trying to reopen previous version of question. Suggested edits were made and it was still closed.
