# Revision history [back]

This bug is fixed in sage 5.10 (trac ticket 14578), and you will now get the following answer :

{0: 0, 1: Z^25, 2: 0}


But a previous answer of @vdelecroix suggests that the answer could be:

{0: 0, 1: Z^18, 2: 0}


Perhaps there is a problem somewhere, what should be the right result ?
