I suggest you post to the forum at viewforum.php?f=708. This forum is for Registered Joomla! User Groups which are groups of people that meet together in their local areas. https://community.joomla.org/user-groups.html.

Mod: can you please move this to Joomla 3 administrator?

That said, you can find the IDs when you go to Users -> Groups and then the ID is in the far right column.

$parent_group_id = 2;
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id')->from('#__usergroups')->where('parent_id = '.(int)$parent_group_id);
$db->setQuery($query);
$children = $db->loadColumn();
// returns an array of group ids
