| Mar 7, 2018 at 17:41 | comment | added | HJRW | @MarkSapir — you’re right; I of course meant the class of known linear groups. I think this was pretty obvious from the context. | |
| Jan 20, 2018 at 18:02 | comment | added | user6976 | The class of linear groups did not grow. The class of known linear groups did grow. As far as residual finiteness is concerned linear groups are quite easy. | |
| Jan 20, 2018 at 13:57 | comment | added | HJRW | @MarkSapir , it really depends on where you start. Linear groups have been known to be residual key finite since Malcev, but the class of linear groups grew dramatically in the last 5 years. | |
| Jan 12, 2018 at 15:48 | comment | added | user6976 | The list of known f.p. residually finite groups is not "big": linear groups, f.p.$Aut(G)$ where $G$ is any residually finite group, f.p. $Out(G)$ for some residually finite groups $G$ (satisfying the Grossman properrty), and parts 2 and 3 of my answer (in 2 one can replace "free group" by any f.p. linear group). That is it, as far as I know. | |

| Jan 11, 2018 at 19:40 | comment | added | Yiftach Barnea | @BenjaminSteinberg I thought big-list means CW automatically. But maybe it has changed or I just misremembering it. But I don't think I can do it? Or am I wrong? | |

| Jan 11, 2018 at 16:59 | comment | added | Benjamin Steinberg | Also this should get turned to CW first I suppose since it is a big list type question. | |

| Jan 11, 2018 at 13:21 | comment | added | Benjamin Steinberg | I'll do it later if someone doesn't do it first. For an answer I would want to find the exact references and a link of possible. | |
| Jan 11, 2018 at 13:16 | comment | added | Yiftach Barnea | @BenjaminSteinberg you might like to put it all as an answer, just for completness. | |

| Jan 11, 2018 at 13:06 | comment | added | Benjamin Steinberg | There is a nice survey by Grigorchuk, Nekrashevych and Suschsnskii in the proceedings of the Steklov Institute. I think Grigorchuk has it in his homepage. Grigorchuk and Sunic have a survey called self-similar groups and there is Nekrashevch's book on self similar groups for more advanced learners. Bartholdi and Silva also have a survey. | |

| Jan 11, 2018 at 11:03 | comment | added | Yiftach Barnea | Thanks @BenjaminSteinberg. Can you suggest a good survey? | |
| Jan 11, 2018 at 10:38 | comment | added | Benjamin Steinberg | Automata groups are residually finite and fairly concrete. | |
| Jan 11, 2018 at 10:09 | comment | added | Name | A group is residually finite if and only if it can be embedded inside the direct product of a family of finite groups (from wikipedia). | |
