comb_count_surjections_v1_1218484723_711
A teacher wants to assign 3 different tasks to groups of students, where each task must be done by at least one student and every student is assigned exactly one task. The number of students $n$ is determined by the formula $n = \sum_{d=1}^{3} \varphi(d) \left\lfloor \frac{3}{d} \right\rfloor$. How many ways can the st...
