I have written the following code in a cell:
%gap
OnChains:= function( c, g )
local i, k;
for i in [1..Length(c)] do
k[i] := OnSetsSets(c[i], g);
od;
return k;
end;
But when I try and run
G.orbit(Set(K[0]), action = "OnChains")
in a sage cell, I get:
Error in lines 1-1

Can someone help me implement my custom group action?
