I do not visit that thread any longer. Brings back bad memories.

Triangular arrays? And can you give an example of such an unsolvable problem that you app creates?

So,the purpose of your app has failed? Or am I not noticing something?

Either way,I am looking at the hyperoperations material on wiki. Do you have any problems on that subject?

How's it a success if it was designed to create unsolvable problems?

Yes. Definition of unsolvable (by me):

There exists an element (which we will call man) from the set P (people) such that the problem B(n) is less than the knowledge of the element man.

By this definition,your problem is not unsolvable,thus it is solvable.Q.E.D.

Hmmmm. But your proof only holds for the set called man. Shall we examine how he is solving them?

The property knowledge of the element man is not closed under the set P. It extends to the set C (computers)

That is extraneous. There are only a few ways to solve them.

It may or may not hold. The point is, the app is an amazing success. Only he can do them. For now that is...

New Question:

A person has a fair die, a fair coin and a 4 color spinner. The spinner has sections marked 1,2,4 and 8. Each with a probability of 1 / 4.

He throws the die and whatever number comes up he flips the coin that many times. He spins the spinner as many times as heads comes up from all the coin flips.What is the probability that the sum of the spinners spins is less than 5?
