Assuming you are referring to the short story "Seven Floors" by Dino Buzzati, here are three literary elements:
1. Symbolism: The seven floors in the story represent the different stages of life and the journey towards self-discovery.
2. Irony: The protagonist, the resident on the seventh floor, believes that he has found the solution to all of life's problems, but in reality, his obsession with order and control leads to his own downfall.
3. Foreshadowing: Throughout the story, there are hints that the protagonist's desire for perfection will not end well, such as when he contemplates jumping from the window and when the superintendent warns him about the danger of the gas stove.
