Pre-pre-pre-block (or pre3-block) is a pentaplet (i.e. a polyplet containing five cells). It is a predecessor to the pre-pre-block (and thus the block), and is the second extension of pre-block.
As a still life component
As a still life component, it has two established names:
- Long hook, usually when attached to an appendage such as a tail or nine, as shown below.
- Feather, as shown below.
