Here’s the challenge: each frog sits on a vertex of a cube, leaving exactly one corner empty. A move is only allowed if a frog jumps over another frog—landing at the point that is the reflection of its position across the jumped frog.
In math terms: if frog A jumps over frog B, its new position is
👉 A′ = 2B − A
This is a geometric reflection (or a 180° rotation around B).
Sounds simple… but here’s the twist:
Can you create a sequence of these reflections so that any frog lands exactly on the one empty vertex?

💡 What’s really happening under the hood:
* Each corner of the cube can be represented as coordinates like (0,1) in 3D → binary vectors in {0,1}³
* Each jump preserves a hidden invariant (a property that doesn’t change), related to parity and vector sums
* The system behaves like a constrained transformation group over discrete space
This is where geometry meets algebra—and intuition often fails.
