Presentation

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

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

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