the number of chess positions overpass the infinite for one number.........the number of combinations for pizza is one number before the infinite xD
Fermat's Last Pizza

As an aside, now that I have the margin (for error). Did you know that: "What is Santa's favourite pizza?" has been voted the worst Christmas cracker joke in Scotland?

That has to be the worst Christmas cracker joke I have ever heard!

Strictly speaking, I should have said: There is a greater variety of pizza TOPPINGs (not pizzas) than there are chess positions. Given that you can order the same pizza twice, there are clearly more pizzas than toppings.
I wonder if you (waiit) are confusing pizza with pasta. They sound quite similar. The number of different pastas is certainly less than infinity.

you are being too deep for the plebs sir
kindly explain the joke please
Paradoxically, so was the pizza - as described in Good King Wenceslas.

Maybe one of the reindeer ate it!
"Good King Wenceslas looked out
On the feast of Stephen
When the snow lay round about
Deep and crisp and even."
This is part of a song (carol) associated with Christmas. The 4th line sounds like a type of pizza: Deep PAN, crisp and even.
Hence, what is Santa's (a character associated with Christmas) favourite pizza?
Perhaps the the extra 'u' in favourite is throwing you?

Yes, it must have been the 'u's. But I got it now! The plebe's and I, we got it. My kids laughed at this thread.
Btw, if you include non-food toppings that end up on little kids pizza's well, that pushes it well over infinity. At least it's stickier than infinity...

You raise an interesting point. Non-food ingredients may render a pizza uneatable - in the limit (if you were not hungry enough, say). This is analagous to unreachable chess positions. Just as the combinatorial explosion of positions makes it impractical to determine when each generatable position is reachable, so it would be extremely difficult to determine whether each possible pizza is eatable - though many (including apparently your kids) have tried.

The solution involves elliptical pizzas, of which every semi-stable elliptical pizza is mozzerella.
This is also known as the Delivery-Di'giorno conjecture.

I don't know much about Bob, but I do know he was often in the vicinty of whalers. I would guess therefore: with blubber? Or something else equally inedible?

on the food subject what way did Bob Marley like his doughnuts/donuts?
good effort Art, answer is "wi' jam in."
and for the follow up how did The Wailers like their doughnuts?

This is also known as the Delivery-Di'giorno conjecture.
Is this the conjecture that is backed by a water-tight guarantee? If it does not arrive within the hour - it's free.
Wasn't it the Dalai Lama who said (eliptically): "A game of chess is like a frozen pizza".
There is a greater variety of pizzas than there are chess positions. (I have discovered a wonderful proof for this, but the margin is not big enough for me to write it.)
