Presentation

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

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

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