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