k列的经验值：
k=1:a（n）=a（n-1）+a（n-2）
k=2:a（n）=2*a（n-1）
k=3:a（n）=2*a（n-1）+3*a
k=4:a（n）=3*a（n-1）+5*a（n-2）+2*a（n3）-16*a
k=5:[顺序12]
k=6:[顺序16]
k=7:[订单22]
第n行的经验值：
n=1：a（n）=3*a（n-1）-2*a（n-2）-2*a（n-3）+3*a（n-4）-a（n-5）；也是一个三次多项式加上一个周期为2的常数拟多项式
n=2：a（n）=2*a（n-1）-a（n-3）-2*a（n-5）+2*a（n6）+a（n-8）-2-a（n-10）+a；还有一个四次多项式加上一个周期为12的线性拟多项式
n=3:[阶27；也是一个5次多项式加上一个周期为840的二次拟多项式]
n=4:[订单61]
