I think benchmarking would be a great idea.
At the very least we could create a suite of benchmarking calculations and each of us could post the results.

@Hullzie16 

So when MetricSearch gives me a list of vacuum solutions, it does not mean that the stress-energy is automatically zero in for the given metric if the metric has undetermined functions?

@ecterrab  My question was not about the Petrov Type II, it was about Vacuum Type II.

If it is a vacuum soluiton, the Einstein tensor and the Ricci tensor should be zero right?

@Carl Love Is there a way to color the lines coming out of the poles differently than the rest of the lines?

@ecterrab Thank you. I figured it would be unlikely to supress dependencies automatically. Just wanted to make sure.

@mmcdara 
Exactly what I was looking for! Thank you!

@Carl Love  It works. Thank you.

@Rouben Rostamian  Thank you. It works. I have one more question, Is there a way to ensure that maple writes all possible expressions in the supressed form throught a worksheet?
