With the move of MathOverflow into the SE network, this account is now associated with dormant accounts in math.SE and other sites in the network. While I plan to continue my (generally low-level) participation in MO, my current plans do not include restarting my participation in those other sites. Therefore, I will be ignoring any comments or pings that reach me from those sites, unless and until I resume my active participation there.

I remain "gone for the foreseeable future" from math.SE, tex.SE, and meta.SE.

Please do not send me private e-mail to call my attention to comments, questions, or other matters related to those sites. Thank you. Also, as I no longer participate in those sites, I do not wish to be sent, by private e-mail, questions that you can just as well ask on those sites. I would have thought it was obvious, but apparently I need to say so explicitly.

comment Primitive elements in a free group
I don't think you are asking what you mean to ask, because as written, you can just take $B$ to be an arbitrary free basis, and $B_0=B$, and $K=\aleph_0$. I suspect you want $B_0$ finite, for one thing...

comment non-intersecting families of subspaces
If $r$ does not divide $m$, then $(k^m-1)/(k^r-1)$ is not an integer (e.g., $k=5$, $m=3$, $r=2$, you get $124/24$), so what would "whose size is equal to..." mean in that case? (P.S., is "size" the cardinality, or the dimension?)

comment Generating finite groups using subgroups
Of course, this is just the wreath product $K\wr C_2$; you can see examples with arbitrary index for $G$ by taking $K\wr C_n$ instead.

comment Generating finite groups using subgroups
right: it's just that as you phrased it, the subject of the sentence is "$H\leq G_0\leq G$", for which "is a subgroup" makes no sense.

comment Generating finite groups using subgroups
"Suppose that $H\leq G_0\leq G$ is a subgroup of index $2$..." You mean "suppose that $G_0$, $H\leq G_0\leq G$, is a subgroup of order $2$", right?
