Presentation

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

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

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