Sample space for a die with three 1s: {1,2,3,4} or {1,1,1,2,3,4}?

[Zamouregal]

A six sided dice has the numbers 1,1,1,2,3,4.
What is the sample space?
Is it 1,2,3,4 or 1,1,1,2,3,4?
Could you please explain why?
All of my classmates are arguing about this question.

The "sample space" is the set of all possible outcomes. A set does not have repetitions.
