Thank you very much for your quick answer.
Unfortunately, I tried what you say, and I don't get any output.
The first time, it says "available properties insufficient to compute 'SCHLEGEL_DIAGRAM.VERTICES'"
The second time, it just remains silent. Visualization via '$p->SCHLEGEL;' is still fine.
Below is a dump of what I wrote.
