Dear Gianni and Roger, Thank you very much for the clarifications. Gianni's table is especially clear about the two cycles of 12 for Italic hours as used in the Muslim world.
Chris Lusby Taylor's comment is true in a way but, equally, your original remark can be interpreted as being correct. You said: Also for each point of the line of horizon (on the sundial) pass one hour line with Modern, one with Italic *and* one with Babylonian hours. I interpreted this as being *correct*. The horizon line IS either B=0 or I=24 so you have triple points like B=0, F=8, I=16 and B=8, F=16, I=24. These points are on the horizon line! I do agree that HMOD=11, HIT=22, HBAB=2 is an inconsistent trio but it can be made correct just by changing HBAB to 0 and you have another triple point on the horizon line!
