Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=gh,b^2=gh,c^2=h,b^a=bf,c^a=cg,d^a=di,c^b=ch,e^b=ef,e^d=ef
