Maybe we could reserve for undergraduates competitions like the ones that
Andrew suggests, and for high schoolers something more along the lines of
using the OEIS  to assist in brute force number crunching.

As an example of what I'm talking about:


This references three prime numbers listed in the OEIS, and knowing that
could help speed up the factorization. But perhaps the number would have to
be larger so that it's not so easily factored by a sophisticated program
like Mathematica, which on its own tries different factorization methods to
tackle large numbers.
