Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 128

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

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

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