Iterability of exp(x)-1

[andydude]

I can port it to Maple and Sage, but it will take about a week.

I recommend Sage for poor mathematicians, because it is free, and combines dozens of open-source CASs.

For more root-tests for the coefficients, see:

• DE^[-1/2](x)
  
• DE^[1/2](x)
  

And for more of the coefficients themselves, see:

• First 100
  
• First 50 (if you don't want 100)
