Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 30 points:

(16,17)(18,22);(7,8)(9,12)(10,11)(13,14)(15,16,19,17)(18,20,22,21)(23,24,27,26)(25,28,29,30);(4,6)(8,11)(12,14)(16,17)(18,22)(25,29)(28,30);(3,4)(5,6)(7,8)(9,12)(10,11)(13,14)(15,17,19,16)(18,20,22,21)(23,25)(24,28)(26,30)(27,29);(1,2);(7,9,10,13)(8,12,11,14)(15,18,19,22)(16,20,17,21)(23,26,27,24)(25,28,29,30)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((16,17)(18,22), (7,8)(9,12)(10,11)(13,14)(15,16,19,17)(18,20,22,21)(23,24,27,26)(25,28,29,30), (4,6)(8,11)(12,14)(16,17)(18,22)(25,29)(28,30), (3,4)(5,6)(7,8)(9,12)(10,11)(13,14)(15,17,19,16)(18,20,22,21)(23,25)(24,28)(26,30)(27,29), (1,2), (7,9,10,13)(8,12,11,14)(15,18,19,22)(16,20,17,21)(23,26,27,24)(25,28,29,30));
