In a chemistry book I’m doing, there is a symbol for proportionality that looks like an 8 turned sideways, with one end open. I found the symbol on the internet, but can’t find a braille symbol. Can anyone help me with this?

Sounds like it could be variation?
See page 144 (12) in The Nemeth Braille Code For Mathematics And Science Notation, 1972 Revision (Green Code Book).

If you don’t have the (Green) Nemeth Code Book the dots for this are 456, 123456.
You would put a space before and after the variation symbol.
Hope this helps.

The only other thing that I found in the Nemeth Code Book that could resemble an 8 turned sideways, with one end open is on page 23.
The Greek lower-case alpha (ordinary lower-case a).

Thank you for answering the question posted here. You are correct that the braille symbol for this is 456, 123456. It stands for proportionality.
