A permutation of the natural numbers from 1 to 116.

The table has 32 columns and 6 rows:

.H.He.Li.Be .B..C..N..O

.F.Ne.Na.Mg Al.Si..P..S

Cl.Ar..K.Ca .Sc.Ti..V.Cr.Mn.Fe.Co.Ni.Cu.Zn.Ga.Ge.As.Se

Br.Kr.Rb.Sr ..Y.Zr.Nb.Mo.Tc.Ru.Rh.Pd.Ag.Cd.In.Sn.Sb.Te

.I.Xe.Cs.Ba (La).Lu.Hf.Ta..W.Re.Os.Ir.Pt.Au.Hg.Tl.Pb.Bi.Po

At.Rn.Fr.Ra (Ac).Lr.Rf.Db.Sg.Bh.Hs.Mt.Ds.RgUubUutUuqUupUUh

The Lanthanides and Actinides are not expanded above.

The first 4 columns contain 6 elements each, the next 14 columns (not detailed above) are the Lanthanides and Actinides, then there are 10 columns with 4 elements each and the final 4 columns with 6 each.
