It is on page 339 of English edition. Unfortunately, Google preview rejects to show this page to me (but I may read the table of contents). |

I have a Russian edition. This is Chapter 10, Section 31, Subsection 3. |

Invariant planes of a nilpotent matrix with two Jordan blocks of size two
This is the description of all of them, because any invariant subspace containing a vector $v$ shoud contain $Nv$. |

Take any vector $v$ not belonging to the kernel of $N$ and consider the space $\langle v,Nv\rangle$. This family and the kernel of $N$ are all spaces you ask about. |

An element $g$ in a group such that neither $g=1$ nor $g\ne 1$ can be proved.
