Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

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

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