正则表达式匹配不确定重复

从一堆手机号码中，找出xyz可不连续且重复3次的手机号码

`package test;

import java.util.regex.Matcher; import java.util.regex.Pattern;

public class Main {

public static Pattern pattern=Pattern.compile("(\\d{3})(.*\\1){2}");

public static void main(String[] args) {
    String s1="13620446688";
    Matcher m1=pattern.matcher(s1);
    System.out.println(m1.find());

    String s2="13613613600";
    Matcher m2=pattern.matcher(s2);
    System.out.println(m2.find());

    String s3="13601360136";
    Matcher m3=pattern.matcher(s3);
    System.out.println(m3.find());
}

}
