In P226 the graph of a 4-D hypercube is divided in four parts of 8 lines
each, adding up to the complete structure of 32 lines. The algorithm was described and discussed at large in my exhibition catalog DIMENSIONS,
Galerie Mueller-Roth, Stuttgart, 1979. In the example below, four such sets of 8 lines each are placed in a magic square. |

The first version of the algorithm from 1978 did not include the possibility of rotating the 4-D hypecube. In rewriting the code I got inspired by graph-theory and immediately found with this the solution I was looking for. This algorithm generated successful programs like P224, P225 and P226 from which I made many drawings and paintings. Years later in 1987, I wrote another version of this code by introducing the 4-D rotation of the hypercube which generated again a successful workphase Dimensions-II, see P411a, or P411b. In 2017, out of curiosity, I had a new look at the first version of my code from 1978 and suddenly became interested in persuing this handicap of "no-rotation". I used the original code with its rigid position of 45-degrees in all angles and directed the algorithm into a different visual solution. Again, the basic 32 lines which constitute the hypecube are divided into 4 sets, but this time the elements are called randomly and placed in a linear visual 4/4 rhythm. |
