  We have carried out a quantitative analysis of the $1^{\circ} \times
1^{\circ}$ region near star-forming site AFGL 5157 using 'Minimal Spanning
Tree' (MST). The analysis reveals that this region consists of five major
clusters. The cluster radii of the cores and active regions were found to be
varying between 0.75-2.62 pc and 2.77-4.58 pc, respectively, for these regions,
while the aspect ratio varies between 0.71 to 7.17. This hints towards the
clumpy as well as elongated clusters in the region. We calculated structure
parameter Q for each region which varies between 0.41-0.62 and 0.23-0.81 for
the cores and ARs, respectively. This shows the existence of fractal
distribution in all the cores and ARs except the core of the [HKS2019] E70
bubble.
