L notation

Hm, I found two papers using L notation, and both use it without the big O. On the other hand, the reference given at Wikipedia's article (Handbook of Applied Cryptography) provides the definition with the O. I don't know whether there is a primarily accepted definition or not, and which one it is. I will try finding out more about it in the mean time. Nageh (talk) 18:38, 9 August 2010 (UTC)[reply]
