The number $n$ is computed by summing $\varphi(d) \cdot \lfloor 3/d \rfloor$ for $d = 1$ to $3$. For each such grouping, there are $5!$ ways to assign cluster labels. How many labeled clusterings are possible?

geo_count_lattice_rect_v1_53965629_8
Let $a = 120$ and $b = 29$. Compute the number of lattice points in the rectangle $[0, a] \times [0, b]$. A lattice point is a point $(x, y)$ where both $x$ and $y$ are integers. The rectangle includes all points such that $0 \le x \le a$ and $0 \le y \le b$. Compute the number of such points.
