k列的经验值，明显重复出现7*k-4级：
k=1:a（n）=a（n-1）
k=2:a（n）=a（n-1）+2*a（n-2）-a（n-3）+3*a（n-4）-a
k=3:[顺序17]
k=4:[订单24]
k=5:[订单31]
k=6:[订单38]
k=7:[订单45]
第n行的经验值，显然是n+3次多项式：
n=1:a（n）=n^4+2*n^3+2*n^2+n
n=2:a（n）=n^5+（3/2）*n^4+2*n^3+（3/2
n=3:a（n）=n^6+（16/15）*n^5+（13/6）*n*4+（5/3）*n|3-（1/6）*n$2+（4/15）*n
n=4:[七次多项式]
n=5:[八次多项式]
n=6:[九次多项式]
n=7:[10次多项式]
