There is something wrong with the title. The horizontal line is 1, 3, 4, and the vertical column is 1, 2, 3.

This topic should start from 2 and 4, which may be 16, 25, 36, 49, 64, 8 1. Because the amount of classification is too large, here can only provide my ideas, and it takes too long to answer this question. I hope the respondents in the back can answer it.
