Presentation

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

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

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

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