Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

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

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

Polycyclic presentation:

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