    Matrix groups and conjugate

    Please see attached file.
    I understand that for part a K is a normal subgroup of L through strategies eventually equating with a lower traingular matrix such like L. But when i try to manipulate H i end up with a really weird final result?! such as fractions and a lengthy multiplication in the bottom left corner. Any help would be appreciated.

    And any pointers on b) would be an extra bonus!

    Many thanks, Hanna.

    Hi Hanna,

    I leave to you the determination of conjugates, but here's an answer to the first part:

    If you have problems with the conjugates, reply to this posting.
