[Blindmath] Nemeth equivolent for Logical Not

[Rose]

On page 133 Rule XIX Section 137 it states:
Tilde: This sign of operation is used predominately in logic with the 
meaning of /not. /dots (4, 156)

The logical not symbol that you show is the "half turnstile looking" 
logical not and I know that this does not translate correctly with any 
translation software that I have used. I have seen some transcribers 
substitute the tilde, but what ever is being used will need to be 
defined for you on a special symbols page/notes etc.

If it is represented as a tilde ~ then it would translate as that ... dots (4, 156), but sometimes the print will use what looks like "half turnstile"  which looks to me like a left pointing arrow with only a straight left lower barb, this symbol is not in the Nemeth code, but I have seen it transcribed as the arrow it looks like dots (1246, 6, 1256) or simply as the "shape indicator n" dots (1246, 1345).
