Section dimension[edit]

Section dimension: "For example, the transformation R4 → R4 described by the matrix above maps all of R4 to some four-dimensional subspace."

Shouldn't it be "... some three-dimensional subspace"? See what it says in the paragraph directly over: "the 4 × 4 matrix in the example above has rank three."
