Presentation

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

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

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