Triple

Target class: Conway group
Context triple: [Co1, instanceOf, Conway group]

• A. Conway number
  A Conway number is a recursively defined number system introduced by John Conway that generalizes real numbers and ordinals, allowing arithmetic and game-theoretic values to be represented within a unified framework.
• B. finite simple group chosen
  A finite simple group is a finite group that has no nontrivial normal subgroups, meaning its only normal subgroups are the trivial group and the group itself.
• C. finite reflection group
  A finite reflection group is a finite group generated by orthogonal reflections of a Euclidean (or more generally, real inner product) space, acting as symmetries that preserve distances and angles.
• D. subgroup
  A subgroup is a subset of a group that is itself a group under the same binary operation, containing the identity, inverses, and being closed under the operation.
• E. pseudogroup
  A pseudogroup is a collection of local homeomorphisms (or diffeomorphisms) on a topological space that is closed under composition, inversion, restriction to open subsets, and gluing of compatible local maps, generalizing the notion of a group action to local symmetries.
• F. None of above.
