### Re: ProjectEuler twitter bot

Have you ever looked at projecteuler.net?

If you solve a problem over there you get a forum dedicated to that problem.

So your ideas are very,very redundant.

Before coming up with all kinds of extensions (really?) please solve a few problems first.

### Re: Problem 752

You can verify that (1+sqrt(7))^12=2757056+1041920*sqrt(7) (see also your screenshot of Wolfram)

2757056 mod 5=1 and 1041920 mod 5=0

2757056 mod 5=1 and 1041920 mod 5=0

### Re: Resouces to get better at solving Project Euler problems?

There's also another approach possible: Use the Wikipedia and Mathworld sites to study the subjects for which you are missing crucial information. This will need an active wish to learn. E.g. among the first 100 problems are a set around Continued Fractions. I have a masters degree but never learned...

The elements of the set dont have to be whole numbers?

Its a bit confusing as the other questions have only integers.

### Re: Problem 039

There is another condition: m and n should have different parity.

The coprime triple that generates (5,12,13) is m=3 and n=2

The other set (m,n) is 5,1: 25+1=26. 25-1=24 and 2*5*1=10 which gives 10,24,26. But because m and n are both odd it's not a valid coprime triple.

### Re: Problem 039

It's not stated that the solutions must be primitive.

In fact none of the given solutions is primitive:

{20,48,52}=4*(5,12,13)

{24,45,51}=3*(8,15,17)

{30,40,50}=10*(3,4,5)

But these information are basically accessible to everyone who only need to provide an email address to create an account...? If people want to read those data they can make an account, can't they? Why copying them elsewhere? No need to do so. And why do you ask if you don't accept the answer No? O...

Logged in users only information is not for nothing logged-in-users-only information.

So the answers seems me to be not OK.

### Re: Number of solvers for the latest 160 problems

Vamsi, I've taken a look at your weblog. Here is something from the entry for problem 1: The solution is pretty elementary; it does not use the formula for the sum of first n terms of an arithmetic progression. This is by-design, I do not want to use any extra fancy-math when an elementary solution ...

The number of unique solvers in the range [600,750] I don't have. For some other reason I processed the solvers of problems 726 through 747 yesterday. As you know #747 is the most recent problem at the moment. The number of unique solvers with a public account for these problems is 708. That's more ...
