Tricolor Triangle

Discrete Mathematics Level 5

An equilateral triangle with side length \(33\) is divided into \(33^2\) smaller unit equilateral triangles each with side 1, forming a triangular lattice. We color each segment of length 1 either Red, Blue or Green, subject to the condition that each small unit equilateral triangle has 3 sides with either 3 different colors or all the same color. If there are \(N\) distinct ways to color this triangle, what is the value of \( \lfloor \log_9 N \rfloor \)?

This problem is proposed by Hendrata.

Details and assumptions

Two colorings are distinct if at least one segment is colored differently.
Rotations and reflections are considered distinct colorings.
