Multiply this set of numbers by any number of 7, and the result is either an integer multiple of 7 or an integer multiple of 36! This set of data is also closely related to 9, 1+4+2+8+5+7 = 27, 2+7 = 9, whether the six 9s add up to 54, 5+4 or equal to 9, and finally they are all related to 9, for example, 14+28+57 = 90. In addition to this cycle, there are many laws that repeat like lanterns.
