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