Hi,

Use hklview to look at the diffraction patterns, if you print the
h0l zone for both, you will almost certainly see the relationship
straightaway.

In your case the diagonal of the ac plane of one setting is the
same length as the a axis of the other setting, etc. etc. So 
they are indeed the same cell, indexed differently in the ac
plane (the b axis is unique, and therefore has to be preserved).


Hope this helps,

Johan
