This is where things get confusing, though. Prior to 1890, chapters that were established after a previous chapter had folded were given that chapter's designation letter. Then, at the 1890 convention, it was determined the second chapters would use the letter Beta to preface the chapter letter to show they were the second chapter of that letter and closed chapter letters would not be re-used. Chapters that were closed and then later reinstated use the designation "Deuteron" (a small delta set superscript to the letter) for the Greek term meaning "second".

So theoretically:

Beta Gamma: University of Wooster, Wooster, OH - 1876-1914
Beta Beta: St. Lawrence University, Canton, NY - 1881-1903, 1915
Beta Zeta: University of Iowa, Iowa City, IA - 1882
Beta Tau: Syracuse University, Syracuse, NY - 1883

could/should have been single-letter chapters considering they were founded before the final single-letter chapter was founded in 1884.
