if you open a 4.1 file in a lower version, like 3.6., the switches in the geometry nodes are disconnected. to avoid you struggle with this issue, i made two files, one native in 3.6. and the other for 4.1 ++

you have two slider to adjust the seamless position new for each number of tiles. it is made to be more flexible to adjust the connected line together, or even leave a little space between.

The "Base Tiles" is the collection which contains the 55 Base Objects.

The "Stage Single" is made to have a single view on a single pattern.

The "Stage Array" let you view the basic array with 3*3 tiles adjusted to each other to get a better view, how it´s fit together.

The "Stage Additional" gives you only a complete overview about all the 55 objects (you can choose by geometry node, if you want to have the original predefined material or one for all)
