Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:

2^9|a^2=f,b^2=e,d^2=ei,e^2=i,b^a=be,c^a=cf,d^a=dh,e^a=ei,g^a=gi,c^b=cg,g^b=gi,d^c=de,e^c=ei,h^c=hi,h^d=hi
