The members of the wide pair C/2001 C5 (SOHO-297) and C/2003 G3 (SOHO-596) could not survive their perihelia due to
the small distances to the sun (like Kreutz group comets). Such wide pairs gave birth to the new groups. So I have looked for
other possible members. C/2010 C6 (SOHO-1804) and SOHO-4800 looked good if I would change their orbits from retrograde
to prograde. And this is the result:
