He proved the 3 squares theorem.

But the point is any natural number can be represented by 4 squares or less. Does that spark your synapses? can you now solve the problem?

I already knew that theorem. Why?

Try to think like that computational guy we know. What would he do with that?

I remember your program and your level of understanding at that time. You are no longer that Agnishom, you are this Agnishom. That model is obsolete. You asked how to do it in M. I ask again, what does the previous posts make you think of?

I understood nothing of the algorithm then, nor do I now. I just translated it from human language to a programming language.

This problem recently came up on Brilliant https://brilliant.org/discussions/threa … e-theorem/

So let's look at an easier problem. Supposing you want to break a number into 8 squares with M. How can you do it quickly? You know M can always get 4 squares for any number and darn quickly too. Why? Because Lagrange, Legendre, Gauss, Cayley and others say so.

No, It is taking forever for my 10 digit number.

You are trying to get them all with that command. We are discussing how to get one answer.

No, 20

But if you can not do 8, how can you do 20? We solve a bigger problem by breaking it up into many smaller ones. Each which is solvable. If you know how to do 4 then how do you do 8?

Please tell me what is the problem that I must solve now precisely

Okay, you do not know the beginning solution so please open up another thread in Computer Math and ask the question clearly. Remember, others will be seeing it.

You want to know how to represent a 10 digit number as a sum of 20 squares. So post that as your question.

Right now you do not know how to even get it in 4 squares.

We will discuss the answer over there.

Ofcourse not!

I want 20 ways to represent a 10 digit number as a sum of 4 squares.

Ofcourse I do!

Not in Mathematica!

I could translate that to M code but it would be a poor idea.

Very poor. Generally, M is for functional or rule based programming. Procedural code is always slower.
