Lightspeed Slash Notation

The Lightspeed Slash Notation was created by PlantStar, who claims this is one of the fastest notations ever created. It is unfortunately ill-defined, because there is no rule applicable to /1,0,n and further structures just have intuitive descriptions including undefined operations on letters, such as "tetration of letters". Even if we restrict it to the defined portion, the notation is directly defined by Bird's array notation by definition. Therefore it can never be the fastest notation in any sense.

Basic rules

Supposing that @₁ is a string of n-1's "[1" and @₂ is a string of n-1's "2]" and Using Bird's array notation,Its 4 basic rules are:

/n = {10,10[@₁[2/_n2]@₂]2}
/{10,10[@₁[2/_n2]@₂]2} = /0,n
/a+1,n = /a,{10,10[@₁[2/_n2]@₂]2} =
/0,0,n = /{10,10[@₁[2/_n2]@₂]2},0
