Question

The symbol that is a horse shoe what does it stand for?

Answer 1

If you're talking about a horseshoe itself as a good luck symbol:

"One reputed origin of the tradition of lucky horseshoes is the story of Saint Dunstan and the Devil. Dunstan, who became the Archbishop of Canterbury in AD 959, was a blacksmith by trade. The story relates that he once nailed a horseshoe to the Devil's hoof when he was asked to reshoe the Devil's hoof. This caused the Devil great pain, and Dunstan only agreed to remove the shoe and release the Devil after the Devil promised never to enter a place where a horseshoe is hung over the door."

If you're talking about Ω, it's a capital omega, the last letter of the Greek alphabet.
