Number of comets per orbital arc, Oort group, and strand count.

		Number of strands
Orbital arc	Oort group	1	2–10	11+
Pre-perihelion	New	22	34	5
	Intermediate	19	32	5
	Old	5	18	1
Post-perihelion	New	19	24	3
	Intermediate	23	16	3
	Old	11	13	0

Notes. Each entry tallies how many comets have pre- or post-perihelion data, of which Oort group and with how many strands. E.g., there is only one dynamically old comet with more than ten strands pre-perihelion.
