*240 curves @ 11e7

OOOps! I seem to have caused a problem!

I submitted the composite to the reservation page, because that's what was in my clipboard. The reservation page dropped the whole hcn, apparently assuming the submitted number was a prime. factordb says it is a composite.
Yes, this has happened before. The server checks the cofactor for primality, but it doesn't check the submitted factor. Fivemack will have to restore this composite. Tom?
