An improved version of Rainbowlabacus.
Bramlabacus is an Astolabacus-type puzzle suggested by Bram Cohen at the Twisty Puzzles Forum, inspired by Rainbowlabacus. Wheras Astrolabacus has symmetry, this symmetry is broken in this puzzle by having 6 beads in some parts and 8 beads in other parts, in the ordering 868866. This change is intended to make the puzzle more complex to solve.
Obviously other configurations are also possible. Image 6 shows 868686.
