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