Presentation

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

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

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