Presentation

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

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

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

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