A reminder - we still have some "Metamath 100" challenge problems that
would be great to complete. The full list of "proofs to be done" are here:
https://us.metamath.org/mm_100.html#todo
For your convenience I've copied the list below.
No, we're not expecting anyone to do #33 (Fermat's Last Theorem)
right now, but some of these seem relatively within our grasp.
If you're not planning to do one, but have tips on how to do it, please post a reply.
But it'd be even better to have more done :-).
