Bedlam cube
The Bedlam cube is a solid dissection puzzle invented by British puzzle expert Bruce Bedlam.[1][2]

[edit] Design
The puzzle consists of thirteen polycubic pieces: twelve pentacubes and one tetracube. The objective is to assemble these pieces into a 4 x 4 x 4 cube. There are 19,186 distinct ways of doing so, excluding rotations and reflections.
Although the Bedlam cube is essentially just the logical next step up from the 3 x 3 x 3 Soma cube, it is much more difficult to solve.
[edit] History
Two of the BBC2 'dragons', Rachel Elnaugh and Theo Paphitis, were to invest in the Bedlam cube during the second series of Dragons' Den. They offered £100,000 for a 30% share of equity in Bedlam Puzzles. Danny Bamping (the entrepreneur behind Bedlam cube) finally chose a bank loan instead of their investment, as seen in the relevant "Where Are They Now" episode of Dragons' Den.[citation needed]
[edit] Records
The official world record for assembling the Bedlam Cube is 7.77 seconds, and was set by Aleksander Iljasov (Norway) on 28 September 2007.[3]
