The upper bound of edges of the generalized cactus graphs
Sounds good! $\phantom{...}$

Representability of finite metric spaces
By the way, important to note that the matrix is $n\times n$ (and not $(n+1)\times (n+1)$) :)
comment
The upper bound of edges of the generalized cactus graphs
Hello! Do you have any results about these 2-cactus graphs in which every edge belongs to at most 2 simple cycles?

There is also $(d p)=(2 3) $ :)

Sets meeting and avoiding computable sets
@JoelDavidHamkins Thanks, Richard Shore told me about that at some point but a reminder was helpful.

@JoelDavidHamkins I think Spector constructed a minimal Turing degree using "uniform" trees and those don't suffice to force bi-immunity. Can you do fusion arguments with those trees?

@JoelDavidHamkins I don't think he advertised it as such, but maybe.

Solve system of logical equations
Doesn't quite fit with XOR-SAT en.wikipedia.org/wiki/… so I don't know.

I added an example for "If M is a finite monoid, then all minimal left ideals of M are isomorphic as left M-sets" now :)
