If there's a bug, what would my next step be? When I do only induced 
volume, I don't get the correct result. Also, I see 
in https://trac.sagemath.org/ticket/16045 that people are able to use both 
induced volume and lrs engine at once. Is this some previous version of 
sage in which the error wasn't there? How could I circumvent the problem?
