The presentation got a lot of graphics so I can´t post it here but I put it up on my blog if someone cares to take a look.

The two complement to an odd number represented by a binary radial combination will always be perpendicular. Sets of even numbers twos complement got similar symmetric proprieties.

The two´s complement for the set of even integers represented by binary radial combinations colored pink can be found by rotating Pi/2^3=Pi/8 within the set - illustrated by the animation below: The two´s complement for the set of even integers represented by binary radial combinations colored yellow can be found by rotating Pi/2^4=Pi/16 , that is to say Pi/2*n within the set - illustrated below: The binary radial combination represented by orange color only consist of one element and will have it self as twos complement And lastly - the twos complement for the number 0 will result in a carry outside the system – sort of hitting the infinity wall for this universe and a loophole to the next universe (from n=4 to n=5 in the case above). Above symmetries can be found in ring system n=0 ..... n=5 and can probably proven for all n by induction by generating the Thue Morse sequence in a L-system similar to the way that it can be proven that a given diagonal will consist of a radial combination and it's one complement (see the presentation)

The general patterns for the sums in a n-system of the sets starting from the odd numbers going anticlockwise seems to be 2^(2n), (2^(2n-1), 2^(2n-2)…. 2^n and lastly 0 (the zero can alternatively be ignored if we exclude it from N). This can probably be proved as a general rule for all n by induction since its true for n=0 to n=5

It can probably also be proven for an arbitrary n by some sort of induction proof since it’s s true for n=0 to n=5

As in the animated example below where 9 is added to 12 giving the result 21. Subtraction can be done by finding the two complements according to the rules established above.

 July 17th, 2019, 05:47 PM #8 Newbie   Joined: Jun 2019 From: Sweden Posts: 10 Thanks: 0 The diagonal will consist of two radial combinations that are the ones complement to each other. This is true for all radial combinations in a n=5 ring system and can be proved for all n ring systems by induction, as show below:

A bit surprised no one has commented ...

And good luck with your renovation! Perhaps no one has commented because it's an odd way of looking at numbers. Normally you line them up on the number line and perhaps this circle approach, expanding the Thue Morse sequence, seems a bit awkward. But I do think the generated symmetries and the relations between the numbers are quite intriguing and I would very much appropriate if someone cared to take a look. But I also understand that people got other things to do and/or are into some other areas of math or thinks this is to odd. Generating the ring system is quite simple by expanding the Morse Thue sequence starting from the inner circle filling neighboring cells clockwise with 0 and a 1 by applying the L-system (0 → 01), (1 → 10) as shown in the animation below The inner circle represent 2^0, the first ring 2^1, the next ring 2^2 and so on. Binary radial combinations can then be represented by the combinations of ones and zeros generating the numbers 0 to 31 in binary in the example above. At first the numbers might seem to be rather randomly displaced but, as shown above, there are some very interesting patterns and symmetries hiding in the way the natural numbers are arranged.
