Presentation

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

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

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

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