(related to Problem: The Mandarin's "T" Puzzle)

There are many different ways of arranging the numbers, and either the $2$ or the $3$ may be omitted from the "T" enclosure. The arrangement that I give is a "nasik" square. Out of the total of $28,800$ nasik squares of the fifth order this is the only one (with its one reflection) that fulfils the "T" condition. This puzzle was suggested to me by Dr. C. Planck.
