The Bloody Sunday operation was so vast with over 200 men taking part, that unraveling who was with which group is difficult, but I do not believe impossible
As far as I can see now, there were around 15 groups assigned to different houses. Many of these groups found their targets were not at home.
Each group had about 2 men assigned from Collins central organisation (probably the men who did the killing) and Intelligence man who was responsible for picking up papers, and about a dozen others. The groups varied in size, presumably depending on a combination of the numbers of targets in a house, and the complexity of the ground layout.
It would seem that each house was then the responsibility of one company or battalion (I am not clear yet which), and that most men attacking that house came from the one company
I have a list here of the Squad members plus additions made from Active Service Units over time and which houses they attacked (where I know)
