### Suggestion - Link to Fastest Solvers from problem page

If you have not solved a problem, the problem page does not have a link to the "Fastest Solvers" page. I think this would be nice to have. I often modify the URL by hand to replace "problem" with "fastest".

### Re: Problem 493

The problem statement is absolutely clear to me. I don't understand what you mean by the differents variations you list. I don't think there is a correct forum for discussing unsuccessful solution attempts, but if you've looked up the solution already then you can make a post in the closed forum wit...

### Re: Problem 084

To be fair, there are many different probabilities posted in the closed forum. Many solvers had different interpretations of some details and had to do some guesswork. I remember very clearly that I could not reproduce the probabilities given in the problem and I did find the problem a bit frustrati...

### Re: Problem 437

Yes, you may assume that a primitive root modulo $p$ is less than $p$.

You should be able to find many examples with an exhaustive brute force search.

On another website that I visit regularly I had to resort to a custom CSS rule to *hide* tags that are everywhere spoiling my fun. traxex, Would you be willing to share the address of that website, please?

### Re: Organize / Display type of problem

Problem 345 (https://projecteuler.net/problem=345) is clearly a Grid / Matrix type problem and telling that wouldn't help in any way. I think that's because "Grid / Matrix" is such a vague category that it would not be very interesting. Similar websites that do use tags might have ones for linear a...

The recent problems page used to have a message at the top saying "Problem xyz will be published in H hours, M minutes" when a new problem was near. Problem 624 is coming soon, but I don't see this message. I think it was very useful for people in different timezones. The News page says that 624 is ...

### Re: Problem 623

Can you please give the lambda-calculus representation for each of the four lines of code? They were meant to explain why $(\lambda x{.}(\lambda y{.}(xy)))$ and $(\lambda x{.}(\lambda x{.}(xx)))$ are not $\alpha$-equivalent, but $(\lambda x{.}(\lambda y{.}(yy)))$ and $(\lambda x{.}(\lambda x{.}(xx)...

### Re: Problem 623

Scoping in lambda calculus works very much like in C-family languages. Consider these two lines of pseudo-code: { string x = "foo"; { string y = "bar"; print(x, y); } } { string x = "foo"; { string x = "bar"; print(x, x); } } They are not equivalent, because the first one prints "foo bar" and the se...

### Re: Problem 259

The problem can be solved very comfortably in under 10 seconds. It doesn't require a scary amount of computation. I think there are multiple reasonable ways to count distinct expressions that lead to different results. I saw only one count in the dedicated thread and it differs from yours, but you c...

### Re: Errors/Warnings/Bugs

That's interesting. Perhaps there was an issue with some specific browser version in the past?

I noticed that you made the change already, thanks a lot! I visit Project Euler from shared or public computers quite often and being able to read the overviews without downloading them is nice.
