I have read Wiki-pedia, the theorethical key page however does not list if there's a key signature with 6 double flats and 1 flat. The max that that page lists are key signatures with 3 double flats.

    What is the point of this question? How could any answers be useful? What can be achieved by any key sig. with bb or x that can't by simple b and #? – Tim Dec 25 '19 at 11:31
  • the minor key with 6 flats where that key's tonic is modified with an additional flat. how is this a real question rather than trivia? – Michael Curtis Dec 26 '19 at 17:57

At https://en.wikipedia.org/wiki/Theoretical_key

the key you're looking for IS mentioned. 6 doubles plus 1 adds up to 13 flats. It's in the list.

You could also have worked this out from first principles. C major has no flats (or sharps). C♭ major therefore has ALL the flats, 7 of them. Similarly, G♭ major has 6 flats. G♭♭ major will have those 6 plus EVERYTHING flattened again. That's 6 plus 7 flats.

I trust this information will be of great practical use to you!

    @TechnicGoblin5R: According to the edit history of the Wikipedia article in question, the additional keys were added to the article on 31 March 2018. I'm not sure why your web browser would direct you to a version of a page that's nearly two years old. – Athanasius Dec 25 '19 at 4:14
