In the attached PBE+vdW-relaxed geometry of OE62 molecule KEGPOC (64 atoms), what is the maximum pairwise Cartesian distance between any two atoms in the molecule? Identify the two atom rows that attain this maximum. Report the distance in angstrom to four decimal places.

The attachment is one complete PBE+vdW-relaxed XYZ structure, 64 atoms. Coordinates are in angstrom (1 nm = 10 angstrom). Atom rows are numbered starting at 1, immediately after the two header lines. Do not renumber or reorder atoms; use the row numbers exactly as given. This is a single relaxed molecular geometry, not a periodic cell: apply no periodic images or symmetry expansion.
