I'm looking for anyone who's heard of/had contact with/knows anything about a national men's GLO called Sigma Mu Sigma. It seems to be (or have been, it might be defunct) a college fraternity exclusively for Freemasons. It has some connection with the Square & Compass Club, and a GLO called Sigma Alpha Chi that died out in the 50s (no relation to the modern SAC sorority).
I would search old posts, but the search feature won't let you include the word 'mu' in a search because it's too short.
