Sorry, no OG problems. The OG is banned on this forum, per the explicit request of GMAC.

Please read the forum rules. Thanks!

If you want, you can post in the general verbal folder, with a sentence of your own creation that mocks up the structure of this one. If you do so, please cite the OG problem number that you're mocking up.
But under absolutely no circumstances can you reproduce OG content here.

Thanks.
