A four-digit number, if the hundreds and tens are separated by a "comma", then the four-digit number can be written as two two-digit numbers (such as 3162→31, 62). If there is an integer multiple of two two-digit numbers, we call such a four-digit number a "coincidence". Please choose four numbers from the five numbers 1, 2, 4, 6, and 8, and arrange them into four digits. How many "wise numbers" are there in total?
一个四位数，如果在百位与十位之间用"逗号"分隔，那么可以将这个四位数写成两个两位数(如3162→31，62)．如果两个两位数存在整数倍关系，我们就称这样的四位数叫"巧数"．请从1、2、4、6、8这五个数中选出四个数，排成四位数，那么"巧数"共有多少个．
