Tetrahex Butterfly Problem D:
Take a full set of seven tetrahexes.
Remove the 5 (or U) piece
as a body.
Using the remaining six
pieces, make two identical
copies of a three-piece shape for wings.
The solutions are colour
coded as to which pieces are contained in the left wing, and
the 2 (or J) piece is always shown in the same
Many of the solutions are
closely related, with one being capable of changing to
another by swapping one piece on each wing, hence the
solutions are not shown in numeric order. (Note that there
may be more than one solution for a given shape, but only
one example is shown.)
