PIL+ is an Oloexum-Class (formerly Dhaxarum-Class) number. It is an extension of Pseudo-Ineffable Limit (ᚾ), that extends it to the max, it uses some of the same concepts so read that before this.
Definition[]
PIL+ is the limit of the omni-system on every level, PIL+ cannot be described on any thought level as it surpasses the concept of thought levels altogether, collapsed to level 2. We can think of it like the limit of the limit of thought levels, it comes after a never ending sequence of "limit of level 0, limit of level 1...... limit of level w, limit of level w+1..... limit of level PIL.... limit of level PIL+.........." (this means it is past its own thought level), then this is collapsed back through every level back to level 2 (just so that it can actually exist as a concept).
