I bought my birthday, in ddmmyy. 150880 is mine, and I’ll thank you to stop looking so greedily at it.
That made me laugh harder than I have in…well, since I saw the YouTube video of the dramatic lemur that jjtmm posted in that other thread. That was like ten minutes ago.
I bought 6551! It’s my postal code.
Ok…got my zip code…wanna find it? Good Luck!
I got 548968. My childhood phone number! Back from when our phone numbers only had six digits, in the fifteenth century or thereabouts.
Proud owner of 514229, a Fibonacci prime number.
any permutation of the Fibonacci sequence (11235, etc) and pi were taken. As was 333, my favorite number.
I first looked at this thread with no great interest but then saw possibilities.
How exciting it was that I could be the owner of a fantastic prime number.
Then came the fifth Mersenne prime. Now a Fibonacci prime.
What a let down, I feel like a Hick or something.
Like I’m from…Delaware.
822228 for obvious reasons.
I don’t know who these newcomers are, but I’ve already owned 1257219452689 for many years. In fact, I’m actually kinda sorry I bought the damn thing. It really didn’t turn out as advertised. I was thinking about trying to sell, but at this point I’m pretty much willing to just give it away. I’m never going to get around to advertising it and dread taking all those phone calls from people who aren’t that serious. Anybody here want it? I mean, it isn’t worth much, I know, but I’m talking just giving it away for free here, no strings attached. Anybody? For free???
You snooze, you lose.
If you can somehow get me 333, I’ll trade you my Fibonacci prime in a heartbeat.
Allright , you had to throw it back at me.
TAKE THIS!
65,537
The largest Fermat prime known.
Don’t even get me started on it being full reptend prime.
Also the largest prime value of n for which an n-gon is constructible using only a rule and compass. Did you hear me? Only a rule and a compass!
Not to mention it’s the smallest prime which is the sum of a nonzero square and a nonzero cube in four different ways:
65537 = 122^2 + 37^3
65537 = 219^2 + 26^3
65537 = 255^2 + 8^3
65537 = 256^2 + 1^3
Screw Eisenstein and his proofs. Its the largest!
And I own it.
112808 is the 333rd day of this year.
That’s all I got. Even 333 in Hex is taken. 
Why not get an email address instead?
Own a number? <shudder> Oh, no. I’m afraid of numbers. Numbers are scary. Especially seven, as any parent will tell you.
OK, I admit it – that’ll impress the babes at the bar.
I’ll just point out that in an excess of capitalistic fervor, I ALSO own the smallest proven prime Sierpinski number!
So there.
Perhaps today Bricker, perhaps today.
My minions are hard at work to destroy your evil number empire!
78,557 indeed.
691
K-theory !
K-theory !
Aaaaaaaaaaaaaagh!
I think I pulled something.
Help!
Somebody named Jean(really, what kind of name is that?) bought 24601. I bet he never does anything cool with it.
Enjoy,
Steven
