Put houses, trees and animals in some of the empty cells such that identical symbols do not touch, not even diagonally. Additionally, symbols can be partitioned into tripels consisting of a tree, a house and an animal, the latter two vertically or horizontally adjacent to the tree. Numbers at the edge determine how many of the respective symbols can be found in that row or column.
Solution code: The fourth row, H for houses, B for trees and T for animals
