Can a graph have more than one maximum spanning tree with the same weight?

@QuaxtonHale Try some examples! You'll probably be able to figure it out...
It seems possible, since there can be multiple minimum spanning trees
05:43
Right,. when all edges have the same weight.

Q: Do the minimum spanning trees of a weighted graph have the same number of edges with a given weight?

Aden DongIf a weighted graph $G$ has two different minimum spanning trees $T_1 = (V_1, E_1)$ and $T_2 = (V_2, E_2)$, then is it true that for any edge $e$ in $E_1$, the number of edges in $E_1$ with the same weight as $e$ (including $e$ itself) is the same as the number of edges in $E_2$ with the same wei...

@QuaxtonHale Quite right, that's the easiest example. $K_n$ with unit weights has ... many equally good spanning trees.
Uh, that question has been on my todo list for a while...
