Truncated order-6 hexagonal tiling
In geometry, the truncated order-6 hexagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of t{6,6}. It can also be identically constructed as a cantic order-6 square tiling, h2{4,6}

Uniform colorings
By *663 symmetry, this tiling can be constructed as an omnitruncation, t{(6,6,3)}:
Symmetry
Truncated order-6 hexagonal tiling with *663 mirror lines
The dual to this tiling represent the fundamental domains of [(6,6,3)] (*663) symmetry. There are 3 small index subgroup symmetries constructed from [(6,6,3)] by mirror removal and alternation. In these images fundamental domains are alternately colored black and white, and mirrors exist on the boundaries between colors.
The symmetry can be doubled as 662 symmetry by adding a mirror bisecting the fundamental domain.

gollark: Less vaguely, laptops/desktops or other discrete computer-type things will begin to (continue to, actually?) decline as people begin using phones with better dockable IO.
gollark: More vague predictions: computers will generally get faster, but also half the computing power will end up wasted on increasingly flashy animations, poorly programmed applications, and other random nonsense like that.
gollark: Okay, no response right now.
gollark: ?remind 5y "hello future"
gollark: I may or may not have *a* closed timelike curve, but you can only send information that way.
