(six 1.5 inch foam cubes)

Each of the six cubes has a different one of the colors
*red*, *blue*, *light blue*, *green*, *yellow*, and *orange* on each side.
This puzzle is similar to
*Iribako*,
but with a different color pattern.
Like the four block
*Instant Insanity*
puzzle,
the object is to arrange the cubes in a line so that each side has no duplicate colors.
Here is a solution and its corresponding graph
(constructed the same way as for Instant Insanity):

*cycle 1:* Y - 2 - G - 1 - O - 4 - LB - 6 - R - 3 - B - 5 - Y

*cycle 2:* Y - 3 - O - 6 - G - 5 - LB - 1 - B - 2 - R - 4 - Y

*Note:*
W. Baeck has written a program to find six distict solutions,
one being the solution shown above,
and some employing two smaller cycles to form a solution half
(1,
2,
3,
4,
5,
6).
