Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 30 points:

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

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