Summary of a claim published in openai/math; not a claim by this platform.
The claimed group simultaneously has infinitude, simplicity, finite presentation, and amenability. These are precisely the four existence properties requested, with no separate construction method imposed on the answer.
Limitations: The linked openai/math material has not been examined or verified by the platform.

OpenAI's claim
OpenAI presents a proof in the selected manuscript. An infinite finitely presented amenable simple group is claimed to exist.Mathematical statement of the claimed result
Result 1.
The existence claim is \[ \exists G:\quad |G|=\infty,\quad G\text{ finitely presented},\quad G\text{ simple},\quad G\text{ amenable}. \] Here simplicity excludes proper nontrivial normal subgroups. Both ordinary finite presentability and infinitude are part of the assertion.Outline of the argument
Boolean polygons over a quadratic ring define a Stone space and piecewise translation tables. Track and slot comparisons give perfection and simplicity, while finite presentation is obtained from the controlled polygon moves and the translation geometry supplies amenability.Formal verification
For family 253, the documented entry is the single infinite, finitely presented, simple amenable existence example. The listed Comparator files areSimpleAmenable.lean. Named declarations include OAI.SimpleAmenable.main. This site has not executed the Lean code. The scope descriptions do not certify the remaining manuscript arguments.Status caveat
OpenAI attributes these manuscripts to work by an internal model. Its release cautions that arguments without formalization can contain mistakes. This catalogue has not independently checked the proofs; the labels report the mathematical claims attributed to OpenAI.Sources
