⌊ n ! ( n + 1 ) ( n + 2 ) ⌋ \left\lfloor \frac{n!}{(n+1)(n+2)} \right\rfloor ⌊ ( n + 1 ) ( n + 2 ) n ! ⌋
represents the greatest integer less than or equal to
n ! ( n + 1 ) ( n + 2 ) \frac{n!}{(n+1)(n+2)} ( n + 1 ) ( n + 2 ) n ! . Find all possible values of
⌊ n ! ( n + 1 ) ( n + 2 ) ⌋ − ⌊ 1 32 ⋅ n ! ( n + 1 ) ( n + 2 ) ⌋ × 32. \left\lfloor \frac{n!}{(n+1)(n+2)} \right\rfloor
- \left\lfloor \frac{1}{32} \cdot \frac{n!}{(n+1)(n+2)} \right\rfloor \times 32. ⌊ ( n + 1 ) ( n + 2 ) n ! ⌋ − ⌊ 32 1 ⋅ ( n + 1 ) ( n + 2 ) n ! ⌋ × 32.
