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

Polycyclic presentation:

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