Subject: Plumbers Cross?
There have been discussions of Plummer's Cross which I believed to be
unique. Lets have an almost visual representation such as the following
for one face:
X Y X
def
Y Y Y === (Y,X)
X Y X
(O,B)
Then Plummer's Cross looks like (W,G) (G,R) (B,Y) (Y,O)
(R,W)
(and this gives the coloring of my cube as well). The point about this
configuration which I am stressing is that opposite sides have no colors
in common.
Now I find there is a second cross for which the point above is not valid.
This cross takes a form (Y,G)
(R,B) (O,W) (W,O) (B,R)
(G,Y)
Is this known by any Cubists out there?
