Hi,
Any ideas how how to typeset something like the attached array?
How do you get those big brackets there and make sure everything else is aligned?
You can't use an array in an array can you?

Thanks

if you want to do all this in one array, then you may have a problem. you would have to arrays within an array and that will take up too many characters. it can probably work

if you are fine with doing three separate arrays however, modify the following code:

$\text{Initiation}:~~~~\left \{ \begin{array}{rcll} I & \longrightarrow & R & \text{blah blah blah} \\
R & \longrightarrow & U & \text{blah blah blah} \\
Babboon & \longrightarrow & ? & \text{blah blah blah} \end{array} \right.$
