The Euler Characterisitc can be computed from the dimensions of the Z homology of a space.
Are there any other invariants that can be computed from the dimensions of the Z homology?

How about the Betti Number.?

yes - the Euler Characteristic is the alternating sum of the Betti numbers.
 
I'm not sure one could say the betti numbers are computed using the dimensions of the Z homology :smile:

right - the betti numbers are the dimensions
