Re: [isabelle] calculational reasoning for transitive relations
Tried now and it works, including with all combinations:
transtitivity of <o versus <=o, of <=o versus <o, of <=o versus =o, etc.
Thank you, that was easy. :)
This database-driven customization style for Isabelle does marvels, I should
more familiar with it.

I think all you need to do is declare the transitivity rules with the
[trans] attribute. Have either of you tried this?
