Presentation

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

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

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