在行列可自由变换的条件下，5点结构有34个
(A,B)---6*30*2---(0,1)(1,0)
让A分别是5a1，2，…，34，让B全是0。当收敛误差为7e-4，收敛199次取迭代次数平均值，得到

这里训练集A-B矩阵的高度是5，而结构有5个点，5=5因此这个顺序是5点结构的s1顺序。
在行和列可自由变换的平面上3点结构有6个
这个顺序3a1，3a2，…，3a6是训练集A-B矩阵的高度等于6的顺序，而点的数量为3，6>3因此这个顺序是3点结构的s2顺序。这里用5点结构的s1顺序去标定3点结构的s2顺序。
12（3a1+2a1）=5a1+2*5a3+5a4+5a9+3*5a10+2*5a12+2*5a24
3a1+2a1形成5a1的结构可能有非常多的可能

因为训练集A-B矩阵的列可以自由变换对迭代次数没有影响，所以a和c，b和d是同一个结构。
这里a的迭代次数是3716是5a1的迭代次数的1.01倍，b的迭代次数是3863是5a1迭代次数的1.05倍。所以a和b与结构5a1并不相同，但如果认为训练集A-B矩阵的行也可以自由变换则a，b和5a1相同，虽然这将导致误差，但简化了计算。
再计算搜索难度
(1.00+2*1.29+2.24+3.19+3*3.37+2*3.77+2*7.10)/12=3.40
用3点结构构造5点结构，可以通过3点结构+1+1的方式实现，因为行列可自由变换的平面上2点结构只有3种
因此让3点结构分别加2a1，2，3就相当于实现了+1+1的操作。
