Business As Usual

Still near Linz, at the RISC/SCIEnce Summer School. Different courses, interesting people, no time to blog. ;)

We were yesterday in Linz for the sightseeing and the conference dinner. ‚T was nice.

And by the way, I have a new puzzle for you. It was told to me by Padraig Ó Catháin. You have two rectangles with one being 3 times the area of other and other being 3 times the perimeter of the one. Find their sides in integral numbers. More difficult question: how many solutions are there?
