Presentation

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

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

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