Specification: Pc Groups (OSCAR v1.4-v1.8)

Profiles: OSCAR v1.4, OSCAR v1.5, OSCAR v1.6, OSCAR v1.7, OSCAR v1.8 Other versions: Pc Groups (OSCAR v1.0), Pc Groups (OSCAR v1.1-v1.3)

In OSCAR v1.4 through v1.8, PcGroup uses a typed _type object and relies on _refs for the underlying GAP data.

Encoding Notes

• Use a typed _type object whose name is "PcGroup".
• Store the parent-group reference inside _type.params.
• Resolve the underlying GAP payload through _refs.

Canonical Example Payload

The following payload is taken directly from the current rosetta-stone corpus.
