... Let us note that by elementary linear algebra we can prove that the condition (1) is equivalent to F being an orthogonal transformation; if F is expressed as a matrix AF it will be an orthogonal matrix, and as such it possesses a lot of nice properties, as is well known from linear algebra. For ins ...
