Presentation

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

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

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