# Context Free Grammar \$L=\{a^ib^{2i}c^{2i} | i>1\}\$

In one of my exams I needed to find a CFG for $$L=\{a^ib^{2i}c^{2i} | i>1\}$$.

however, it really seemed to me that it is not a CFG. I tried to show it is not using the pumping lemma, and think I managed, but I don’t really know if I did something wrong there.

So was I wrong or the question is wrong?

Thank you.
