Minor comment to the post (v2): Please consider to mention explicitly author, title, etc. of link, so it is possible to reconstruct link in case of link rot.

comment On the Lorentz Group representation
However, reviewers are voting to migrate it to Math.SE. I close this question as a homework-like question, partly to prevent it from being migrated to Math.SE.

comment On the Lorentz Group representation
This question (v2) seems like an archetype of a math problem encountered in many areas of physics, e.g. QCD, and which the community consistently wants to not migrate to Math.SE, cf. this meta post.

Hi toshiomagic. Welcome to Phys.SE. If you haven't already done so, please take a minute to read the definition of when to use the homework-and-exercises tag, and the Phys.SE policy for homework-like problems.
