Hi Dmitry,
If you would look at the help page, you would see there is no "group" option in ChimeraX "sym" command. 

<https://rbvi.ucsf.edu/chimerax/docs/user/commands/sym.html>

From looking at it myself, the option to use the symmetry from another model is "symmetry", so try this:

sym #2 symmetry #1

I hope this helps,
Elaine
