A puzzle designer creates $S(7,5)$ distinct ways to group 7 unique tokens into 5 non-empty indistinguishable boxes, then assigns $5!$ different labels to the boxes. The total number of labeled configurations is $M$. If the designer subtracts $M$ from 2584, what is the remainder when this difference is divided by 98467?

Find the remainder when $ 44121 \cdot r $ is divided by $ 66571 $.
