Abstract: Equilateral triangles of sidelengths 1, 2 - t , 3 - t , 4 - t , ... can be packed perfectly into an equilateral triangle, provided that 1 / 2 < t ≤ 37 / 72 . Moreover, for t slightly greater than 1/2, squares of sidelengths 1, 2 - t , 3 - t , 4 - t , ... can be packed perfectly into a square S t in such a way that some squares have a side parallel to a diagonal of S t and the remaining squares have a side parallel to a side of S t .
