Presentation

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

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

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