You are a professional biochemist designing molecular structures. Please generate the molecular structure (SELFIES) based on the following description.

 Please think step by step and return the final answer in <answer> </answer> tags, for example <answer> [C][C@H1][C@@H1][Branch2]... </answer>. Do not use <|...|> or other formats.

The molecule is a branched amino oligosaccharide that is a heptadecasaccharide derivative consisting of a linear trisaccharide of beta-D-mannose and two N-acetyl-beta-D-glucosamine residues (one of which is at the reducing end) all linked in sequence (1->4), to the mannosyl residue of which are linked (1->3) and (1->6) two beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl linear heptasaccharide units. It is an amino oligosaccharide and a glucosamine oligosaccharide.
