Sorry, I should have stated it more clearly.  When a number of cards 
all have the same group placed upon them, especially if the group's 
backgroundBehavior property is set to true, they can be said to be 
members of the same group or the same background.  (Former 
HyperCarders find it useful to think in terms of cards on 
backgrounds, which in Rev means cards sharing a common group.)

Once you have this configuration it is possible to refer to cards in 
an order that is specific to all cards that share that group; hence I 
can

   go to card n of group "myGroup"

This implies that there is an internal index that keeps track of the 
order in which those cards were added to the group.  What I'm trying 
to find out is if there's a way to access that index, in the same way 
that I can access the stack's index when I use

   get the number of this card

Any ideas?
