Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 20 points:

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