Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 5 generators on 20 points:

(1,2,3,4)(5,6)(7,13)(8,16,17,11)(9,12)(10,15)(14,18,20,19);(14,20)(18,19);(2,4)(5,7,9,15)(6,10,12,13)(8,14,17,20)(11,18,16,19);(5,8)(6,11)(7,14)(9,17)(10,18)(12,16)(13,19)(15,20);(10,13)(18,19)

Polycyclic presentation:

2^10|a^2=f,c^2=j,c^a=cg,c^b=cfgj,d^a=dgi,d^b=dh,e^a=eh,e^c=egi,f^d=fj,h^c=hj,i^a=ij
