Length 3
This puzzle is the 16-coloured version of the hexagonal tiling. The slices are related to that of the Rubik's cube's or more specifically the Megaminx's, therefore the solution is not difficult.

Andrey:
With 9 colors first stage was easy, but edges are too much connected. The best thing that I could develop was 22-twist commutators for 3-cycle of edges and 10-twist for re-orientation of the couple of edges. And I had to remember them in normal and mirrored forms in all orientations of the plane. Terrible...
Nan:
I just finished my {6,3} 9 colors, 3 layer factor = 1.29903810567 (the sweet spot Roice provided). For the edges, I used a 10-move commutator for 3-cycle, which is not too bad. It's actually easier than I expected yesterday. I notice you said your 3-cycle is 22-twist but re-orientation is 10-twist. That's a little weird. For me re-orientation is usually two 3-cycles.
Andrey:
Yes, it's strange for me too.
Let's mark centers as
I've started with commutator [A,E']. Among other things it moves three edges around center D and changes orientation of two of them. So when I made [[A,E'],D^2] (10 twists), it was pure reversing of edges DF and DG. But I failed to make pure 3-cycle from it. Then I tried [A,E]. Again, it moves 9 edges, and the best I made from it was 5-cycle [[A,E],C^2]. Third commutator converted it to 3-cycle: [[[A,E],C^2],D^2]. Not very good, but enough for solving.
Nan:
Your reorientation algorithm is interesting. Using your notation, my 3-cycle is [[C,E],D] = (C,E,C',E'),D,(E,C,E',C'),D'. D can be replaced by D2, D3, D', etc to get some variations.

Possible strategy
(1) Collect the edges first with normal twists then with the 3-cycle sequence S1 = [[A,B2'],[D2',C]] , B and D second layer, A and C first layer
(2) Do the face-edges with the 3-cycle sequence S2 = [A,B]^5 where A is layer 1 and B layer 2
(3) Do the edges as I have indicated in KleinsQuartic Document
(4) Do the corners as I have indicated in KleinsQuartic Document
(5) Do the face-corners with the 3-cycle sequence S3 = [ C'DA2 [A,B'] A2'D'C , [A,B'] ] all second layer turns except D
