Looking for the name of a puzzle

This puzzle looks like 5 bricks. You have to draw a continuous line through each wall. I am looking for a solution and name of the puzzle. How would I search this site for it not knowing the name?

Two brick on top. Three on the bottom. Line must pass thru each connecting wall. 16 walls. Can only go thru a wall one time.

The puzzle should look like:

I'm pretty sure the puzzle is not on this site, as problems are generally submitted just as text, there are only a few that rely on an image.

This problem is impossible, anyway. There are three regions with five sides, and two regions with four sides (it does not matter that some of the walls are shared between regions). If you have a region with an odd number of sides, the line must begin or end in that region. Since the continuous line will have only two endpoints, it's impossible to solve this puzzle.

There is still a poor guy trying to solve it, if you look here.

My sentence that got cut off in the previous post (stupid pre tag) said, most problems are submitted as text, and there are only a few that rely on images, and I'm fairly sure that we haven't seen this problem.

It's a pretty good problem. I think the one where you have to draw that diagram with only 3 strokes is good too. (This one is impossible too)

The top result from a Google search on Euler puzzle rooms is this .

Re: Looking for the name of a puzzle

Thanks for the help. One of my co-workers had this puzzle stuck in his mind by an elementry teacher. Drove him crazy.

Re: Looking for the name of a puzzle

I believe there was an article in "Scientific American" many years ago that presented this problem and explained why there is no solution (as DJ did so well above). I was first exposed to this problem by my seventh grade math teacher years ago. I wasted many, many hours, as did everyone else in my class, trying to find the solution to this unsolvable puzzle. At least it kept us busy and out of trouble!
