I respectfully disagree... I believe the default HSRP group of 0 (zero)
will be invoked.  It would only not work if the other HSRP participants
were configured to use group 1.  This is a common config mistake, where 
specific groups are created (say, to permit identification of unique
HSRP participants via the HSRP MAC address that would be created), and you
omit the group number on one or more of the commands.  But in the provided
example, standby group 0 is created, with HSRP MAC address of 00-00-0c-07-
ac-00 being mapped to IP address 1.0.0.4 by the active router.
