Seeing numbers 1137 and variations of it like 113, 137, 3

As title suggests, for years now I have been repeatedly seeing the numbers 1137. Whether it be the time, the seat number in my lecture hall, a number I am assigned, the number I keep rolling on a D20, etc. I also see variations of it like 113, 137, or plain old 3. 3 is actually my favourite number, and it has been for years and years. What does 1137 mean?
