This doesn't really matter but it does occur to me that you can't really reasonably debate where the Fibonacci sequence starts, because if it started at 2, then 1 wouldn't be a Fibonacci number. But indeed, it's not only a Fibonacci number, but the only one to be in the sequence twice. (You can of course skip ahead if you have some need to do so.)
