Description

Design By:

Bruce Love (1987)
Made By: Jerry McFarland
Material: Maple
Size: 3 inches
Availability: Discontinued
Of the 35,657,131,235 different 'holey' 6-piece burrs, only this one requires this many moves. The next closest burr requires 10-moves to remove the first piece. A complete computer analysis of these burrs was run from 1987-1990 by Bill Cutler with assistance from about 10 other people.

Love's Dozen was discovered by Bruce Love before the computer programs were run.

There are many ways to assemble the pieces into a 6-piece burr, but only one of them requires 12 moves. The 12-move solution is the only one in which the markings make the letters 'D' on the ends.

Winning bidder shall pay for shipping. Estimated Europe 13GBP; USA etc 17GBP; UK cheaper
Happy Bidding

********************************************************************************
To make this auction fairer if the leading bidder has changed any time during the final day, that lot will remain open for an additional day. This will continue until the leading bidder has retained the lead at least one full bidding day. The purpose of this rule is to give the penultimate bidder a reasonable time to counter-offer, and thus to discourage poaching. I feel this is the right thing to do as some bidders are in different time zones and may not be able to bid towards the end, unless they like sleep deprivation. This method is used on various other puzzle auctions.
