Topic #1 --- The { Odd-On-Odd Format } explained :

The { Odd-On-Odd Format } for { positive 'odd' integers } is based on the fact that :

Let us now look at a quick example , for the number [ 67 ] , as follows :

We can then write :

We then identify :

Topic #2 --- Table for { 0 < N < 64 } :

Let us now take a quick look at the { Odd-On-Odd Equation } & the { Odd-On-Odd Format } for { 'odd' numbers < 64 } , as per this table below :

Let us take note , first-of-all , that we have marked-off , for the { Odd-On-Odd Format } ,

This then mark-off the place where the value of the expression { jumps from [ 1 ] to [ 3 ] } ,

Secondly , for { N = 1 } , we have repeatedly applied the { 2nd anchoring equation } , i.e. the equation :

This then illustrate the importance of this { 2nd anchoring equation } :

And this is comparable to adding { a bunch of [ 0's ] } to the [ LEFT ] of the { 1st occurance of a [ 1 ] } in a { binary format } , reading left-to-right :

The reader will also notice that , for any given value of [ N ] :

We shall explain why this is so in the next { Topic } below .

Topic #3 --- The { Odd-On-Odd Format } vs. the { Binary Format } :

Let us now divide the { positive 'odd' integers } into layers , such that :

We then have this table below for the 1st six (6) layers :

Layer
I.D.
Defining Condition
for the layer
Anchoring
Number
for the layer
i = 1 2 < N < 4 3
i = 2 4 < N < 8 5
i = 3 8 < N < 16 9
i = 4 16 < N < 32 17
i = 5 32 < N < 64 33
i = 6 64 < N < 128 65

And the { Anchoring Number } for each layer , on the very-right column , is given by :

We then have this table below for the four (4) [ anchoring numbers ] for { Layer 2 thru 5 } , for illustration purposes :

Let us now take a look at the expansion of the four (4) [ anchoring numbers ] :

This then shows why the { Odd-On-Odd Format } always matches the { Binary Code for the digits to-the-left of the [ unit-digit ] } , for these & other { Anchoring Numbers } :

Let us start-off again with an [ anchoring number ] and change a [ blue-color-ball ] to a [ red-color-ball ] :
