Printing compile-time integer sequence in C++11

So I'm doing a bit of homework where I have to write my own compile-time integer sequence in C++11 and write a few functions for it (print, concat, sort etc.) but I'm having a bit of trouble wrapping my head around how I would go about writing these things.

template<typename T, typename Comp = std::less<int>>
struct Facility{

    template<T ... Nums>
    struct List{

        struct Element<T ... nums>{};

        template<unsigned num, T val, T ... rest>
        struct Element{
            unsigned index = num;
            T value = val;
            Element<index-1, rest...> others;
        };

        template<unsigned num, T val, T ... rest>
        struct Element<0, val>{
            unsigned index = 0;
            T value = val;
        };

        static constexpr Element<Nums...> elem = {};

        static void Print()
        {
            // Prints out the list
        }
    };

};

using IntList = typename Facility<int>::List<intlist...>;

int main()
{
    using List1 = IntList<1, 2, 3>;
    List1::print()
}

I'd just like to know if I'm on the right track so I don't work myself into a dead end. I'm not 100% sure on the static print and the static constexpr member in List, though I can't think of any other way to make it work.
