It got 2 down votes and 3 close votes. What's wrong with it?
It originally contained the single statement
Classify (up to ring isomorphism) all semisimple rings of order 720.
A valid reason to downvote (hover over the downvote button to see) is that
This question does not show research effort
which the question did not. This explains the downvotes. Some people who have the power to vote to close (including me) feel that such questions also should be closed until research effort is added. That explains the votes to close.
Now that this question has been somewhat improved, such measures are not necessary, but of course people who downvoted or voted to close may not yet have seen that the question was edited, and therefore they have not removed them. I have now retracted my downvote and vote to close.
