The thumbnail images below compare the original on the left with the minibrot at A and B. The magnification increases as you go down the page. Arms means how many arms are around the minibrot before it goes through a period doubling (or halving). The fractals look similar for the first two rows but then look very different. I only made an image when the number of arms changed.

The image on the front page is a slightly zoomed in version of the left most image of row two. The color palette log offset is adjust differently as well.

Size is the width in fractal space. Size can be converted to FractInt magnification with the relation: magnification = 2.666 / size.

No equivalent shape. The original fractal has 8 straight arms in this area.

    Period halving. Each even armed shape contains a minibrot. The center exit shape leaves with straight arms unlike the image to the right which has spiral arms. If you zoom into either 8 armed "candelabra" shape you would come to another shape like this one. Our path is down the center. Size = 5.0E-46 Period halving. Each even armed shape contains a minibrot. The center exit shape leaves with spiral arms. The arms interconnect differently than the one to the left. Size = 1.6E-63

    Period halving. Zoomed to minibrot. The parameter file (beaz60) for this image is located on page 4. Size = 3.8E-60 Period halving. The minibrot can just start to be seen as the white dot in the center. Zooming deeper reveals the minibrot, but has features too fine to show up well in thumbnails of this size. The parameter file (bebz94) for this image is located on page 4. Size = 7E-94

 

 

In conclusion, the deeper minibrots have finer detail farther away from the center as you would expect. The original only has period doubling while A and B have period doubling and period halving. The period halving is associated with candelabra shapes that each contain a minibrot. It appears that any structure with an even number of arms always has a minibrot in it (except the two arm spiral). Zooming in on any minibrot away from the original seems to add period halving.

Zooming in on a minibrot on a spiral revealed a minibrot with spiral arms approaching it as well. Zooming in on a minibrot on a straight section had all straight arms.

I hope you enjoyed reading this short exploration into the mandelbrot set.
