Type 4

No type of pyramid can have 4 sides, it can have only 4 faces.

A 1974 Volkswagen Camper is a type 2. A type 4 is a different car. Sometimes the enging is refered to as a type 4 engine. Early busses used a bug (or type 1) engine. Later busses 1972- use the type 4 style engine. A type 2 engine is very similar, but a bit different from the type 4 engine. The type 4 engine came with Domed pistons for higher compression. The type 2 ones had flat pistons.

4 is composite.
