Combinatorial encoding data
Plantri embedding: [[1,2,2,3],[0,3,4,5],[0,6,7,0],[0,7,8,1],[1,8,8,5],[1,4,6,6],[2,5,5,9],[2,9,9,3],[3,9,4,4],[6,8,7,7]]
PD code (use to draw this loop with SnapPy): [[5,20,6,1],[4,9,5,10],[19,6,20,7],[1,11,2,10],[14,3,15,4],[15,8,16,9],[7,16,8,17],[18,11,19,12],[2,13,3,14],[17,13,18,12]]
Permutation representation (action on half-edges):
Vertex permutation $\sigma=$ (11,20,-12,-1)(16,3,-17,-4)(12,5,-13,-6)(1,6,-2,-7)(7,18,-8,-19)(15,8,-16,-9)(9,14,-10,-15)(19,10,-20,-11)(4,13,-5,-14)(2,17,-3,-18)
Edge permutation $\epsilon=$ (-1,1)(-2,2)(-3,3)(-4,4)(-5,5)(-6,6)(-7,7)(-8,8)(-9,9)(-10,10)(-11,11)(-12,12)(-13,13)(-14,14)(-15,15)(-16,16)(-17,17)(-18,18)(-19,19)(-20,20)
Face permutation $\varphi=(\sigma\epsilon)^{-1}=$ (-1,-7,-19,-11)(-2,-18,7)(-3,16,8,18)(-4,-14,9,-16)(-5,12,20,10,14)(-6,1,-12)(-8,15,-10,19)(-9,-15)(-13,4,-17,2,6)(-20,11)(3,17)(5,13)
