Presentation

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

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

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

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

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