k列的经验值：
k=1:a（n）=a（n-1）
k=2:a（n）=a（n-1）
k=3:a（n）=a（n-1）+2*a（n-3）-2*a（n-4）
k=4:a（n）=a（n-1）+4*a（n-3）-4*a（n-4）
k=5:a（n）=a（n-1）+6*a（n-3）-6*a
k=6:a（n）=8*a（n-3）-11*a（n-6）+4*a（n-9）
k=7:[顺序13]
第n行的经验值：
n=1:a（n）=2*a（n-1）-2*a（n-3）+a（n-4）；也是二次多项式加上一个周期为2的常数拟多项式
n=2:a（n）=a（n-1）+a（n-3）-a（n-5）-a；还有一个二次多项式加上一个周期为12的常数拟多项式
n=3:[阶18；也是二次多项式加上周期为840的常数拟多项式]
n=4:[订单36]
n=5:[订单70]
