Hehe, a great 7x7x41 for you too pahio!

= 4:2 x 13:1

= (1:2):(1:1) x (6:1):1

= (1:(1:1)):(1:1) x ((1:1 x 2:1):1):1

= (1:(1:1)):(1:1) x ((1:1 x (1:1):1):1):1

Hey Jon, I understand (1:(1:1)):(1:1) x ((1:1 x (1:1):1):1):1, but Could you please explain how this diagram is generated?

### Re: Happy (1:(1:1)):(1:1) x ((1:1 x (1:1):1):1):1, Everybody...

ohh... I deciphered it, explaination not needed anymore

### Re: Happy (1:(1:1)):(1:1) x ((1:1 x (1:1):1):1):1, Everybody...

oh, i cannot resist a redundant explanation ...

"redundancy is the essence of information", y'know ...

what's at root here is a 1-1 correspondence between the set N of positive integers and the set (N ~> N) of finite partial functions from N to N.

writing the ordered pair (x,y} as x:y, we have the correspondence:

1 <-> {} = the empty function
2 <-> {1:1}, since p_1^1 = 2
3 <-> {2:1), since p_2^1 = 3
4 <-> {1:2}, since p_1^2 = 4

usw ...
