We collected the information of 304 gamma-ray bursts (GRBs) from the literature, and analyzed the correlations among the host galaxy offsets (the distance from the site of the GRB to the center of its host galaxy), T 90, i (the duration T 90 in rest-frame), T R45, i (the duration T R45 in rest-frame), E γ, iso (the isotropic equivalent energy), L γ, iso (= E γ, iso/T 90, i, the isotropic equivalent luminosity) and L pk (peak luminosity). We found that T 90, i, T R45, i, E γ, iso, L pk have negative correlation with offset, which is consistent with origin of short GRBs (SGRBs) and long GRBs (LGRBs). On separate analysis, we found similar results for log E γ, iso− log(offset) and log L pk− log(offset) relations in case of SGRBs only, while no obvious relation for LGRBs. There is no correlations between offset and L γ, iso. We also put the special GRB 170817A and GRB 060218A on the plots. The two GRBs both have low luminosity and small offset. In the log(offset)− log T 90, i plot, we found GRB 170817A locates in between the two regions of SGRBs and LGRBs and it is the outlier in the offset− E γ, iso, offset− L γ, iso and offset− L pk plots. Together with GRB 060218A being an outlier in all plots, it indicates the speciality of GRBs 170817A and 060218A, and might imply more subgroups of the GRB samples.
