Antisymmetric relation

In mathematics, a binary relation R on a set X is antisymmetric if there is no pair of distinct elements of X each of which is related by R to the other.More formally, R is antisymmetric precisely if for all a and b in X if R(a,b) and R(b,a), then a = b, or, equivalently, if R(a,b) with a ≠ b, then R(b,a) must not hold.

a computer reading from the book is no different than me reading the book itself. If I'm already confused by how the book is written, this does absolutely nothing by "reading it for me".
