O is the sun.

A is 1.000000…, Venus^0 or Mercury. Of course in the Mercurial system it is also Earth^0, Mars^0, Jupiter^0, etc.

B is 1.366025…, Venus^.5 or .5(sqrt 3 + 1), the square root of the mean orbital distance of Venus and the cube root of the time of orbit of Venus.

C is 1.596570…, Venus^.75 or the square root of the time of orbit of Venus. This is the geometric average between the times of orbit of Mercury and Venus. Its formula can be expressed as sqrt (Venus^1.5) or as Venus^.75 or as (Venus^.5)^1.5. This factor, multiplied by the divine proportion, gives the mean orbital distance of the Earth.

D is 1.866025…Venus^1, mean orbital distance of Venus.

The significance of Venus’ (or any planet’s) .75 power that it is the square root of its time of orbit and therefore the average between its own orbital period and Mercury’s.

The significance of Venus’ .5 power ( or any other planet’s) is that it is the square root of the mean orbital distance of that planet and therefore the geometric average between its own mean orbital distance and Mercury’s.

Or, (P^.5)squared = orbital distance P and (P^.5)cubed = orbital time P.
