Does anybody know a commonly used symbol for WLOG (without loss of generality)? I'm not comfortable with typing the whole thing every time and the abbreviation is just a compromise. If there is one for QED, why shouldn't there be one for WLOG? :)

0There are symbols for QED because it's useful and aesthetic to give a typographic clue that the proof is over. But when doing scratchwork or boardwork WLOG is succinct enough, and in typescript the words would be written out. – 2014-11-26

In German, the equivalent phrases "ohne Beschränkung der Allgemeinheit" (oBdA) or "ohne Einschränkung" is sometimes denoted by Œ (O-E ligature):
Œ $ a

Since there doesn't seem to be any such symbol, I decided to create one, by manipulating $\forall$ and $\exists$. Any thoughts?
