Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:

2^9|b^2=i,c^2=h,f^2=g,b^a=bg,c^a=ch,c^b=ci,e^b=ei,d^c=di,e^d=ei
