"I see... Supracollapse is unchangeable but still can't fall into our dynasty..."
Hammexpansion is a hammeconcept invented by Aarex. This concept supersedes NilGaming's expansion, which takes on the opposite of collapsing. (example: ones below reality are being expanded into ones in real-life)
This process takes all systems on a set and creates the boundless embodiment of all that is uncollapsible under metaprocesses and attachments to these systems. For example, hammexpanding the set of all Supracollapse-level-2 things results with everything that is at least level-3-collapsed or level-3-uncollapsed.
Inexpansible[]
A number is inexpansible if all expanded forms of it aren't bigger on all expanding methods including hammexpansion and others that make embodiments beyond specific meta-boundaries.
Supracollapse might be inexpansible without Mooniasedes. Any hammexpansion would result with a same or higher Supracollapse level that Supracollapse can't collapse into.
Unchangeable[]
A number is unchangeable if it's both uncollapsible and inexpansible. An example might be Boundless-Liferal Numker.
