What happened
A Show HN project by Alen (github: alenvelocity) renders all 43,252,003,274,489,856,000 Rubik's Cube permutations in a scrollable 2D/3D viewer, with presets like Superflip and Checkerboard and scale markers at 1.1×10¹⁹ through 4.3×10¹⁹.
Why it matters
Not actionable for shipping work, but a neat example of compressing an astronomically large state space into a browsable UI — useful as inspiration for how to visualize and navigate huge combinatorial datasets in a web app.
Discussion angle
How do you practically represent and let users navigate a 4.3×10¹⁹-element space without precomputing it — what's the indexing trick here?
