Presentation

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

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

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