Presentation

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

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

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