Zero is not the correct format but a Cambrian Math (italicised) O is shown in
the diagram - should this be
1. ;,o
2. ;O
3. ,o
or just
4. O
bearing in mind of space issues when there are negative numbers on either axis
- and not enough room for transcribers note on the swell paper!
I have scanned the Technical Material Guidelines 2014 and the Using UEB for
Mathematics but not spotted anything so far.
We are still waiting for the receipt of TC21451 ordered in November, not likely
to be received until end of January!
