Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

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

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