24 or 6 to 4
The six pieces of this diagonal burr puzzle create a flattish solid that displays a prominent fourfold symmetry. The pieces are, roughly, two notched sticks, two pseudo-notched sticks, and two Cluster Buster pieces. The pieces consist of 24 blocks, whence the lame name. I've just discovered that two of the pieces are like Michael Toulouzas' 3 Crecos.
