Presentation

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

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

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