In his article Stedman says:
- The planar arrangement differs from the plan of his solid model, 'only as necessary to clarify the presentation'
One the major features is that only two groups, at Si and Y, are considered to be 'truly' branched and that the latter 'is not usually considered in this manner'
- The smaller symbols, such as V under P, aren't necessary but are 'merely offered for consideration'
- Si shows a greater resemblance to Ge than it does to the closer Ti, while Y similarly shows greater resemblance to Lu than to La
- Stedman first drew his first version of this table sixteen years ago (= 1931)
