Hi Ben,
If I'm not mistaken, you use the British Braille Maths Code. So, I
consulted one of the small handful of experts here in the U.K. The
response is as follows.
"Sigma - I assume he is trying to write Greek capital sigma (sum of)
followed by a lower limit sign in which case you need 16 (ch) to
indicate that the r is the lower limit then 56 (letter sign) then r
although I can't quite see what it means mathematically out of context.
Capital sigma is ALWAYS either alone or has limits (lower alone or upper
and lower). The lower limit needs to be shown as 16, I think."
Hope this helps,
George Bell.

Hi,
With DBT, how do I achieve a "sigma-r" (sigma symbol and the
letter r beside it) and what should the braille representation be?
My guess is dots 456 234 (sigma) and 56 1235 (letter symbol and
r).
Thanks.
