How is the tiling that the FF kaleidoscope uses to create the result

I am still trying to guess and find what is the real seed or tiling that is used inside the FF kaleidoscope component

I mean how is cropped and cut the source image inside the FF kaleidoscope?

For example, in the Wallpaper groups filters you can see clearly the seed tiling image that is used to cut the source image

Reading the Kaleidoscope FF Help Page

From this page above The Kaleidoscope component generates a kaleidoscopic pattern based on the image provided by the Source input. Internally, the component 'cuts' a polygonal fragment (the base shape) from the source image and distributes it across the output image to form the pattern

So, really the question is what is the shape and size of the polygonal fragment that is used to cut the source image? (the light cyan shape of the example below)

Mode: Numeric Input Defines the form of the base shape and the way its copies are aligned and distributed across the output image. The following modes are available: Square, Triangle 1, Triangle 2, Rhomb 1, Rhomb 2, Rhomb 3, and Hexagon.

So, if you choose for example TRIANGLE 1, how is the polygonal shape that is used?

And then knowing how is the polygonal shape that is used, maybe can be known how is the tiling that is used

Thanks very much for any possible help

Here below is an example of polygonal shapes with the tiling that is created as result
