Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 20 points:

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