In multiverse theory, where it is supposed to describe ALL outcomes, a mathematical multiverse is the ultimate ensemble and there are not more levels than this, but it doesn't contain all the imaginable universes because, as Max Tegmark himseld quoted in a paper "the mathematical universe hypothesis does certainly not imply that all imaginable universes exist. We humans can imagine many things that are mathematically undefined and hence do not correspond to mathematical structures".(adsbygoogle = window.adsbygoogle || []).push({});

Where would these universes exist in the multiverse theory if there are not more levels than the level iv (universes described by mathematics)? What theory exists for them? Are they just impossible (and because of that there is not any part in the multiverse theory that describe these universes)?
