According to this,

http://poker.sportinglife.com/Strategies/story_55895.shtml it is 1 in 72,193

Can someone confirm that?

I figured it had to be a lot more rare than that.

Assume you have any card.

The odds that the next one is one of the other 4 that match is 4/51

The odds of the 3rd one being one of the remaining 3 is 3/50

and so on.

So it seems to me that the odds of being dealt a pat straight flush would be:

4/51 * 3/50 * 2/49 * 1/48

This is 0.0000040016

or 249,899 to 1.

Am I figuring this correctly?

If not, how do you do this properly?

The reason this came up is that I was dealt a pat straight flush tonight playing 5-Card draw.

What is even more amazing is that on two other occasions, I was dealt a 4-card straight flush -- and I think I've only ever seen a couple of those before.
