A group object contains information about a private channel. Private channels were once known as "private groups." Consider a group object the same thing as a private channel object.

The name parameter indicates the name of the private channel.
creator is the user ID of the member that created this private channel. created is
a unix timestamp.
is_archived will be true if the private channel is archived.
members is a list of user ids for all users in this private channel. This
includes any disabled accounts that were in this private channel when they were
disabled.
mpims is a boolean that indicated if a multiparty im (mpim) is being
emulated as a private channel. For compatibility with older clients, mpims can
appear as private channels unless rtm.start is called with mpim_aware=1.
topic and purpose provide information about the private channel topic and purpose.
Some API methods (such as groups.create) will
include extra state information for channels when the calling user is a
member. last_read is the timestamp for the last message the calling user has
read in this channel. unread_count is a full count of visible messages that the
calling user has yet to read. unread_count_display is a count of messages that
the calling user has yet to read that matter to them (this means it excludes things
like join/leave messages). latest is the latest message in the channel.
