   Format: MarkdownItexI've changed [[Postnikov system]] definition 2 the part saying "The map $X \to im_n(f)$ induces an [[epimorphism]] on connected components" to "The map $X \to im_n(f)$ induces an [[epimorphism]] on [[homotopy groups]] in degree $n-1$". This was a small issue that confused me.

   I’ve changed Postnikov system definition 2

   the part saying

   “The map $X \to im_n(f)$ induces an epimorphism on connected components”

   to

   “The map $X \to im_n(f)$ induces an epimorphism on homotopy groups in degree $n-1$”.

   This was a small issue that confused me.
