 One attempt to analyze omnipotence in terms of unrestricted repeatability is the account of Hoffman and Rosenkrantz. According to their approach, by identifying certain features of (a)–(f), we can find a feature that none of them possesses, and in terms of which an analysis of omnipotence can be stated. To begin, unless it is possible for some agent to bring about a given state of affairs, an omnipotent agent ought not to be required to be able to bring about that state of affairs. But (a) is not possibly brought about by any agent.
