Presentation

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

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

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

GAP

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

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