Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 24 points:

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

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

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