Each of the 5 polygons shown in Fig. -1 have a

superficial similarity to a sunshade or an umbrella,

with “spokes” color-coded blue extending to

all the corners and a numbers-field “fabric”

affixed to the spokes.

Between adjacent spokes that fabric is like a “web”

connecting these spokes to each other;

a typical web is color-coded orange in each of the polygons.

The centers of the polygons are color coded brown.

In each of these polygons

the spokes are continuous, having no interruptions.

Towards the center of the polygons

their ends are abutted against the center and

against each other,

forming a tight circle around the center and

forming a barrier between the webs and the center.

The webs are composed as a triangular number;

a triangular number is a well known mathematical entity.

The spirals shown in these polygons

have the initial increment from origin to next number

pointing towards a corner of the polygon.

On account of all of the above

comparisons between numbers arrays

on these spirals can be legitimately be drawn.

The polygons and associated spirals per Fig. -2 are

non-compliant with the modes of construction

previously described.

** **

In these polygons the spokes do not form

a tight ring around the center and thus

they don’t form a barrier between

the webs and the center of the polygon.

In the trigon:

The spokes are discontinuous, having interruptions.

In both these polygons:

The webs are not composed as a

standard triangular number.

** **

With each of the spirals in these polygons:

The initial increment from origin to next number is

pointing towards a side of the polygon.

** **

On account of the above

comparisons between numbers arrays

on spirals per Fig. -2 and those on Fig. -1

might be questionable.
