Firstly, we introduce the concept of
G
-chain mixing,
G
-mixing, and
G
-chain transitivity in metric
G
-space. Secondly, we study their dynamical properties and obtain the following results. (1) If the map
f
has the
G
-shadowing property, then the map
f
is
G
-chain mixed if and only if the map
f
is
G
-mixed. (2) The map
f
is
G
-chain transitive if and only if for any positive integer
k
≥
2
, the map
f
k
is
G
-chain transitive. (3) If the map
f
is
G
-pointwise chain recurrent, then the map
f
is
G
-chain transitive. (4) If there exists a nonempty open set
U
satisfying
G
U
=
U
,
U
¯
≠
X
, and
f
U
¯
⊂
U
, then we have that the map
f
is not
G
-chain transitive. These conclusions enrich the theory of
G
-chain mixing,
G
-mixing, and
G
-chain transitivity in metric
G
-space.
