No. 24 is a really regular polyomino, a septiamond (using all 24 possible pieces out of 7 triangles)
in a star-symmetric tray. This puzzle is the most difficult one of the 'Beat the Computer' series.
Tenyo's quote: "You are a genius if you find your first solution within an hour,
but not even a fool if you find it in a day".
Even though there exist over 1.000.000 solutions according to Tenyo !!
I can hardly imagin.

With the next plan I found over 10.000 solutions by hand.
The pie sections at the upper side can be mirrored and swapped with each other.
