COMMENTS

A permutation of the natural numbers from 1 to 118.

The number of terms in the columns, also ordered right to left is: 7, 7, 6, 6, 6, 6, 6, 6, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2.

This is a consequence of finding 2*7=14, 6*6=36, 10*4=40, 14*2=28 elements with outer shells of s, p, d, and f-electrons.

Acronymic name: CMMSPT.
