Deltoidal Trihexagonal Tree

This type is an adaptation of Branch (ブランチャー) by Inaba Naoki to a Deltoidal Trihexagonal grid.


Draw segments to create a network such that:

  1. Every vertex • and node O is connected.
  2. Vertices must connect to exactly two path segments.  Every branch of the network must form a path from one node to another.
  3. Numbers indicate the sum of the lengths of every branch directly connected to that node, in segments.
  4. The network is acyclic – there are no loops.
