Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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