Summary
| Description |
English: Spiral of equilateral triangles with side lengths which follow the Perrin sequence. Akin to File:Padovan triangles (1).png. 3, 0, 2, 3, 2, 5, 5, 7, 10, 12, 17, 22, 29... The first two terms may be ignored or the spiral may be considered to begin clockwise (3, 0, 2), and then flip to counterclockwise (2, 3, 2...), with both 3s in the same location. The 3 triangle is marked dark blue to point out it being snubbed. |
