Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 4 generators on 30 points:

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

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

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