What numbers did Sayaka Maizono write on the wall in Dangan Ronpa Trigger Happy Havoc?

In the game Danganronpa: Trigger Happy Havoc, Sayaka Maizono wrote the numbers "11037" on the wall. These numbers are significant because when viewed upside down, they resemble the word "LEON," which refers to Leon Kuwata, a student at Hope's Peak Academy. Sayaka, a pop sensation, intended to frame Leon for her murder so she wrote his name in a way to make it look like a dying message. This cryptic clue plays a crucial role in the investigation and trial that follow, hinting at the true identity of the culprit.
