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.)

the number of chess positions overpass the infinite for one number.........the number of combinations for pizza is one number before the infinite   xD

artfizz included herin as big a margin as you require

waiit proof please - you dont get away that easily

ps anchovies on my pizza please

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?

What is Santa's favorite pizza? 

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

you are being too deep for the plebs sir

kindly explain the joke please

Yeah, sorry.  I don't get it either.

Santa's favourite pizza, deep pan, crisp and even

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.

Paradoxically, so was the pizza - as described in Good King Wenceslas.

Oh that is sooooo bad it is almost funny but definitely witty

I don't get it.

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.

on the food subject what way did Bob Marley like his doughnuts/donuts?

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?
