Given a reference text about LIV Golf, tell me what "LIV" means, when it was started and who financed it.

LIV Golf  is a professional golf tour. The name "LIV" refers to the Roman numerals for 54, the score if every hole on a par-72 course were birdied and the number of holes to be played at LIV events.[1] The first LIV Golf Invitational Series event started on 9 June 2022, at the Centurion Club near London, England. The Invitational Series became the LIV Golf League in 2023.

LIV Golf is financed by the Public Investment Fund, the sovereign wealth fund of Saudi Arabia.
