@GregoryGrant Eisenstein's criterion is not a total free lunch as you have to invoke Gauss' Lemma (also here) or detour into notions of total ramification of primes.

comment Which pairs of matrices generate $SL(2, \mathbb{Z})$?
@HagenvonEitzen thank you. I know $a = b = 1$ is enough to generate all of $SL(2, \mathbb{Z})$ and hopefully there are many others.

I don't know if my model accurately describes continued fractions, but you certainly answered my question.
