| May 21, 2015 at 3:31 | comment | added | Kimball | My understanding is that you want to fill in the whitespace faster, correct? If so, you probably don't want to do all the transformations to the same "depth." I guess if one sits down, it should not be too hard to work out which transformations to apply more. | |

| May 21, 2015 at 2:01 | comment | added | KConrad | Good. It would be helpful to explain where this question comes from. The title is just about enumerating cosets (no algorithm), and it's possible to give a concrete list of coset representatives without dealing with your word task. | |

| May 21, 2015 at 1:46 | comment | added | Pablo Lessa | It doesn't make a difference. I'm defining it as fractional linear transformations not matrices. Multiplying the coefficients by 2 does not change the resulting fractional linear transformation. | |
