Representation of the geometric shapes (including one with a manufacturing defect) and cogs used on Pillar 2

Pillar 2 contains two groups of designs plus a series of numbers on the base. It does not use traditional alphanumeric representations for the main codes.

Geometric Code

Large view of the geometric code

The top code is a grid of geometric shapes. These are shown in a grid of 5 rows by 26 columns. There are 26 discrete symbols. A small number of symbols have what appear to be manufacturing defects - small circles attached to other circles - for more info, see the combined photograph.

I have given each symbol a letter so that they can be represented here:
