Summary

[edit]
Description
English: Centered square numbers, highlighted in red, are found in the center of the last row of the expansion of odd triangular numbers – taking 25 as an example, it is the sum of a square number (rotated yellow square) and the next smaller square number (sum of blue triangles).
