\\ Needs also program from A366803:
up_to = 65537;
rgs_transform(invec) = { my(om = Map(), outvec = vector(length(invec)), u=1); for(i=1, length(invec), if(mapisdefined(om, invec[i]), my(pp = mapget(om, invec[i])); outvec[i] = outvec[pp] , mapput(om, invec[i], i); outvec[i] = u; u++ )); outvec; };
v366805 = rgs_transform(vector(1+up_to, n, A366803(n-1)));
A366805(n) = v366805[1+n];
