I posted this last night, but not sure it went through to the list as I
don't see it in my sent items and I never got any responses.  Sorry if it is
duplicate.

I'm hoping someone could offer an example or advice on how to best use
unordered_set or unordered_map to hold many small arrays of unsigned
integers.
I would like to use the built in hash function rather than have to create
one.  Also, since I have many of these small arrays, keeping the memory
footprint small and the hash time at a minimum are important concerns.

A typical int array would hold 5 unsigned ints.

Maybe someone could offer example code or suggestions.  The samples I see
are always the trivial case of just entering a single number or string as
key or value.

Thanks.
