Pai Gow Tiles

I read there are 35,960 combinations of 32 tiles taken 4 at a time.
I wrote a Javascript program to verify it.
I also read there are 3,620 unique hands.
I used the Unix "sort unique"command on my data and came up with 4,285 UNIQUE hands.
I went back and removed one tile of the 9,L8,L7,5 chop pairs (b/c they have the same rank) which resulted in 20,474 hands and 3,755 UNIQUE hands.
Going wrong somewhere.....
How is UNIQUE hand defined?
How did you get 3,620 UNIQUE hands???
