Arranging the numbers 1 - 216 within the T-hexagon
The magic T-hexagon of side 6 uses the numbers 1 - 216. When making
the arrangement, we used the results of smaller configurations, and
these are expressed in the colouring of the diagram below. We also made
up the inner hexagon (of side 3) with the numbers 1 - 54, thus making
this configuration one of those whose inner hexagon total is as small as
possible.
The result was:

You can download a spreadsheet that shows that
this configuration really does use the numbers 1 - 216 once once one
only, and that the rows do add to 1953 ... in every direction.
Thus the numbers 1 to 63 can be formed into a magic
configuration within a 6-sided figure of side length 6 – now that IS
magic! |
