#### 4.2.12 Arquivos do Tipo GROUP

Esse formato é obsoleto, mas ainda é aceito. It combined the functions of `INST` and `TLIST`, taking a series of transformations and a single Geom (`unit`) objeto, and replicating the objeto under each transformation.

         GROUP ... < matrices > ... unit { oogl-object }

is still accepted and effectively translated into

         INST
         	transforms { TLIST ... <matrices> ... }
         	unit { oogl-object }
