Presentation

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

A minimal faithful permutation representation — 3 generators on 20 points:

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