Dr. Volker Latussek wrote about it:
“I have been thinking and working on FERMAT for more than two years. I had initially planned a puzzle with a box typical for me: a square base and centred opening and three triangles. Preferably equilateral triangles. Despite considerable effort, I could not find discover an exciting solution. So I switched to isosceles triangles, in the end the 45 degree angle imposed itself. The side lengths of the three triangles now had to be chosen in such a way that the solution path I intended could not be shortened and, above all, that there were no other solutions. That sounds simple. But in fact I have never struggled so much to make all the possibilities of three triangles disappear into a cuboid box and only allow exactly the one required solution. Triangles are nasty. If you turn the triangles you will see and feel what I mean. Even though FERMAT's triangles have a nice symmetry as isosceles triangles. Do not be fooled. I recommend first getting to know the properties of the triangles outside the box. First practise with the triangles individually in the box. Spaces disappear, spaces open up again through simple rotations. All in all, I was sure twice that I had found the right set of three triangles, only to learn from friends that I hadn't thought of everything. Today I am sure that FERMAT works. But maybe you also want to become friends.”
