so my previous question got answered pretty well however I have some issues. I want to move the following list to the left(minor indent):

Let $G$ be a group, and let $G = mathbb{Z}_5 = {0,1,2,3,4}$. 

Let $chi:G rightarrow mathbb{Z} = {mathbb{Z}inmathbb{C}:lvert{mathbb{Z}rvert}=1}$. 

Now we have: 

%

begin{align*}

chi{0} &= 1\

chi{1} &= a\

chi{2} &= a^2\ 

chi{3} &= a^3\

chi{4} &= a^4

end{align*}



with $a = exp{frac{2piiu}{5}}$ hence $a^5=1$.

I also want to put the last line of the 'code' in the same line as chi(2), as this looks more professional. also I don't want exp but the actual exponent as it looks much better.

Is this what you wanted?

documentclass{article}

usepackage{amsmath}

usepackage{amsfonts}

%usepackage{showframe}% dubugging tool



newcommand{iu}{text{i}}% just a guess.  couldn't find definition



begin{document}

Let $G$ be a group, and let $G = mathbb{Z}_5 = {0,1,2,3,4}$. 

Let $chi:G rightarrow mathbb{Z} = {mathbb{Z}inmathbb{C}:lvert{mathbb{Z}rvert}=1}$. 

Now we have: 

par% assuming parskip=0pt

begin{minipage}{dimexpr textwidth-parindent}

begin{flalign*}

chi{0} &= 1 &&\% only need it once

chi{1} &= a \

chi{2} &= a^2  \ 

chi{3} &= a^3 \

chi{4} &= a^4 

end{flalign*}

hrule height0pt% a sort of horizontal strut

end{minipage}

with $a = exp{frac{2piiu}{5}}$ hence $a^5=1$.
