At-bash is a basic "reflective" transformation pattern, wherein the first and last letters of the alef-beit transform into one another, as do the second and second-to-last, and so on.
The name at-bash is a reference to the first two of these transformation pairs: alef–tav and beit–shin.
This is the alphabetic transformation whose elements correspond to the sefirot within the partzuf of binah–Imma.
