Does the order of a list matter? If X=<1,2,3> and Y=<3,2,1>, is X=Y? Does the order of a sequence matter? I have been lead to believe these two mathematical data structures are the same, with the exception of order but I cannot remember which has the order restriction. I am using these terms in a University level discrete mathematics context. I tried googling around, but the difference between lists and sequences wasn't upheld in anything I found.

Does the order of a list matter?

What do you mean by "list" here? That's not mathematical terminology.

Does the order of a sequence matter?

Yes.

I have been lead to believe these two mathematical data structures are the same, with the exception of order but I cannot remember which has the order restriction.

The one that where order doesn't matter is a set. The one where order does matter is a tuple (pair if there's only two elements in the tuple, triple if there are three), or "sequence", especially if it's an infinitely long tuple. "List" isn't mathematical terminology and could refer to either depending on the context.
