36  36  Sparse Univariate Polynomial Ring in y over Integer Ring

38   Rings with different variable names are not equal:: 
 38  Rings with different variable names are not equal; in fact, 
 39  by trac ticket #9944, poynomial rings are equal if and only 
 40  if they are identic (which should be the case for all parent 
 41  structures in Sage)::

40   sage: QQ['y'] < QQ['x'] 
41   False 
42   sage: QQ['y'] < QQ['z']
