In the WIKI documentation, at 
<http://wiki.blender.org/index.php/Doc:2.6/Manual/Modeling/Objects/Groups_and_Parenting#Grouping_objects>, 
I noted that while the documentation details how to create a group, and 
add an object to a group, it does not seem to specifiy how to remove an 
object from the group. I think I managed to add that.
