What is the total number of stereoisomers that can be formed by the octahedral complex ion [Co(H2NCH2CH2NH2)(NH3)2Cl2]+[\text{Co}(\text{H}_2\text{NCH}_2\text{CH}_2\text{NH}_2)(\text{NH}_3)_2\text{Cl}_2]^+[Co(H2NCH2CH2NH2)(NH3)2Cl2]+?
(Note: H2NCH2CH2NH2\text{H}_2\text{NCH}_2\text{CH}_2\text{NH}_2H2NCH2CH2NH2 is the bidentate ligand ethylenediamine, commonly abbreviated as en\text{en}en.)
