max nodes

[mitnickhun]

hello

this isn't an issue, but a don't find a forum.
In the documentation is the following:

Node 00 is the base node.
Nodes 01-05 are nodes whose parent is the base.
Node 021 is the second child of node 01.
Node 0321 is the third child of node 021, an so on.
The largest node address is 05555, so 3,125 nodes are allowed on a single channel.

I don't understand this..
As I calculated, there are max:
1 + 1_5 + 5_5 + 5_5_5 + 5_5_5*5 = 781 nodes.

Hint: it helps if you draw a tree with the topology.

"The largest node address is 05555"
it means to me that there are 4 "layers" in the tree + the base node ==> the tree has 5^4 = 625 leafs (nodes).
in the upper "layers" are 5^1 + 5^2 + 5^3 = 5+25+125 = 155 nodes
plus the base node
total 781 nodes.

3125 would be (actually it wouldn't), if the tree had 5 layers (5^5 = 3125 leafs, not leafs+nodes)
