Presentation

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

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

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

GAP

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

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