Presentation

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

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

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