How to produce [ultra] pan magic 15x15 squares
 
 Can you use to produce a 15x15 panmagic square the same method to produce panmagic 5x5 squares?
The answer is yes and no. If you choose as first row the digits 0-1-2-3-4-5-6-7-8-9-10-11-12-13-14 than
you get as result only a semi-magic 15x15 square. If you use the digits 0-2-1-3-4-5-8-7-6-11-10-9-
13-12-14, than you get a correct panmagic 15x15 square.

Notify that the row 0-2-1-3-4-5-8-7-6-11-10-9-13-12-14 leads to a correct result, because 0+3+8+11+13,
2+4+7+10+12 and 1+5+6+9+14 is 35, that is 1/3 of (0+1+2+3+4+5+6+7+8+9+10+11+12+13+14=) 105.
 
 
There is a more difficult method to produce a 15x15 panmagic square (use the digits 0 up to 14 instead of
1 up to 15, because it is easier to calculate with).
 
The difficulty is the construction of the first row (after that it is not difficult anymore). The key to produce
the first row is the rectangle of 3x5 or 5x3:

The magic sum of 0 up to14 is 105. Notify that in the rectangle the sum of each column of 5 digits is
(5/15 x 105 =) 35 and the sum of each row of 3 digits is (3/15 x 105 =) 21. Fill in the digits as follows:
