Anybody can guide me (maybe Simple and fast if there is) to convert my data:

1 A C Z F G
2 G Q R C
3 Z G Q
4 C F
5 O P
6 O X Y J
7 A P X

I have this table with ~1,000,000 records like these 7 records that you see (In real Database A,B,C,... are words in string), Records 1 and 2 are common in G and C value and 2,3 and 1,3 and ...

I want to sync records if they have at least two common value like Records 1 & 2,3,4 (but record 5,6,7 haven't at least 2 shared values with others) and generate a list like this:

1 A C Z F G Q R
2 G Q R C A Z F
3 Z G Q A C F R
4 C F A Z G Q R
5 O P
6 O X Y J
7 A P X

at the end we must have 4 same records if we sort data and one others without sync:

1 A C F G Q R Z
2 A C F G Q R Z
3 A C F G Q R Z
4 A C F G Q R Z
5 O P
6 J O X Y
7 A P X

Thank you for any help.
