Way to go mikeu! But everybody, there is still much to do: Can you write a short essay that makes this an interesting fact? Can you find a reference for this fact? (How do we know its actually true). Can you write a similar question with different wording so that the testbank becomes so large that very few students could read it in a semester?--Guy vandegrift (discuss • contribs) 21:10, 2 January 2016 (UTC)

Here's the reference. It is behind a paywall, but all the facts cited at wp are freely available in the abstract. --mikeu ^talk 23:23, 2 January 2016 (UTC)
