Link to specific sheet in Google spreadsheet
I just did a test by creating two additional sheets in one of my docs. I noted the url of the second sheet (gid=1). Then I created a third sheet and noted that (gid=2). I then switched their places, and the gid remained the same, even after reloading the document.
