cse doesn't seem to get all subexpressions

[moorepants]

I was looking at the result of cse here:

and noticed that I saw several repeated expressions, like b_21 * b_31 and omega_nm * zeta_nm.

Shouldn't these be pulled out as subexpressions?

Could you post the text version so I can test this (without retyping what you have shown)?

I think this came from the work I was doing here:

I didn't post the whole problem because it has a lot of build up. I should export the expression in sol[0][0] and provide it.
