Yeah go ahead and put the users numbers into a SortedSet as well and then you can use the following method to see if a set in your ticket list is equal to the set with the user entry.
SortedSet<int>.CreateSetComparer().Equals(userSet, objectSet);
To get a list of IDs you could do something like this.
IEnumerable<int> GetMatchingSetIDs(SortedSet<int> userSet)
{
IEqualityComparer<SortedSet<int>> setComparer = SortedSet<int>.CreateSetComparer();
foreach (Ticket ticket in tickets) //Where ticket is your ticket class with the sortedsets and tickets is a List of tickets.
{
if (setComparer.Equals(ticket.Set, userSet))
{
yield return ticket.ID;
}
}
}
