Curious hand

[Andrew B.]

Played this hand the other day which has a curious feature:

S: A7643
H: AJ
D: A96
C: 643
S: KJ2 S: QT85
H: 9843 H: QT6
D: KQT3 D: 754
C: K2 C: AT7
S: 9
H: K752
D: J82
C: QJ985

- Can you identify the feature?
- Have you seen more extreme examples of it than this one?

Probably the wrong answers. But I noticed that for each suit, the honors are divided between exactly three hands. And it is a different three hands for each suit.

Another feature is that the four distributions of each suit around the table 5431, 4432, 4333, 5332 are the same as the four hand patterns.

Reversed to prevent the spoiler for anyone still trying to work it out:

Assuming that this is the correct answer, there's a page about this sort
of deal here (ROT13'd):

uggc://oevqtr.gubznfbnaqerjf.pbz/oevqtr/qrnyf/onqsvg/

I think the deals there are from large collections of unplayed hands,
rather than hands that were actually used in live play, though. (Hand
generation software is easy enough to come across so people looking
for statistical oddities in bridge hands tend to generate large
numbers of hands until they find ones with the properties they want.)

And yes, there are more extreme examples in existence (although only
/slightly/ more extreme).

Yes, that was the correct answer. Thanks for the link.
