Enigma 1115: New Christmas star
From New Scientist #2270, 23rd December 2000
Here is another “magical” Christmas star of twelve triangles, in which can be seen
six lines of five triangles (two horizontal and two in each of the diagonal directions). Your task is to place a digit in each of the twelve triangles so that:
• all six digits in the outermost “points” of the star are odd;
• the total of the five digits in each line is the same,
and it is the same as the total of the six digits in the points of the star;
• each of the horizontal lines of digits, when read as a 5-digit number, is a perfect square.
What are those two perfect squares?
