Clebsch, 27 Lines, colored Double Six, 20cm

The famous Clebsch Diagonal Cubic Surface. Its 27 straight lines are colored to show one of its so-called "double-sixes". These two sets of six of the lines which meet in a special configuration. More precisely: A double-six consists of twice 6 lines a_i and b_j, such that the a's do not meet among each other, the b's do not meet among each other, but line a_i meets line b_j if and only if i is different from j. So, each line meets exactly five of the other set. If you need the object in a different size, just contact us. Also, have a look at www.MO-Labs.com for related objects.
