Talk:More than one Left Identity then no Right Identity

Is there any algebraic structure with two left identities and no right identity or vise versa? I can't think of any.--cynic 15:22, 30 August 2008 (UTC)

Yes there is, try Definition:Left Operation and Definition:Right Operation for two. --prime mover (talk) 15:47, 30 August 2008 (UTC)
