Genesis is not epimorphic, so we should find non-CS, inconsistent properties. We would also not be able to produce it as any kind of block. I took the steps of Genesis which were mapped to 2 by h58,

which are 45/44, 49/48, 50/49 and 55/54, and split them in two as follows:

45/44 = 81/80 100/99

49/48 = 245/242 121/120

50/49 = 99/98 100/99

55/54 = 100/99 121/120

I then picked the one of the two possibilites presented in each case for filling the "gap" by choosing the option of least Tenney height, and obtained the following:

1, 81/80, 45/44, 33/32, 21/20, 16/15, 27/25, 12/11, 11/10, 10/9,

9/8, 8/7, 121/105, 7/6, 32/27, 6/5, 40/33, 11/9, 99/80, 5/4, 14/11, 9/7, 315/242, 21/16, 4/3, 27/20, 15/11, 11/8, 7/5, 99/70, 10/7, 16/11, 22/15, 40/27, 3/2, 32/21, 484/315, 14/9, 11/7, 8/5, 81/50, 18/11, 33/20, 5/3, 27/16, 12/7, 121/70, 7/4, 16/9, 9/5, 20/11, 11/6, 50/27, 15/8, 40/21, 64/33, 88/45, 160/81

It is readily verified that this *is* epimorphic, with map h58.

The set of steps for this scale is 121/120, 100/99, 99/98, 245/242, 81/80, 64/63, and 56/55. Geometrically it is more complex than Genesis, with 30 verticies and 65 facets. However, a 4D parallepiped would have 16 verticies and 8 facets so there is a limit to how simple this can get, and I suppose Genesis is not so bad.

i thought my original question made it clear that we were to take

11/10 and 20/11 as auxillaries, not as part of the block.

I don't know how to take something as an auxillary, but we can certainly look at the scale we get by leaving 11/10 and 20/11 out of

Genesis. Is this what you mean? Perhaps you could tell us again what you are actually looking for.

yes, or whatever choice is best. there should be only 41 notes inside

the parallelepiped and whatever other shape you may happen to

investigate (what's the 4-dimensional analogue of a 3-d rhombic

dodecahedron or a 2-d hexagon? i feel that should be the most general

case, and certain vertices may coincide in specific instances,

causing some edges/faces/cells to disappear).
