n=2:[1,2,6/2!,23/3!,104/4!,537/5!,3100/6!,…];
n=3:[1,3,15/2!,102/3!,861/4!,8598/5!,98547/6!,…];
n=4:[1,4,28/2!,274/3!,3400/4!,50734/5!,880312/6!,…];
n=5:[1,5,45/2!,575/3!,9425/4!,187455/5!,4367245/6!,…];
n=6:[1,6,66/2!,1041/3!,21216/4!,527631/5!,15441636/6!,…];
n=7:[1,7,91/2!,1708/3!,41629/4!,1242892/5!,43806175/6!,…];
n=8:[1,8,120/2!,2612/3!,74096/4!,2582028/5!,106459312/6!,…];
n=9:[1,9,153/2!,3789/3!,122625/4!,4885389/5!,230689017/6!,…];
