Presentation

minimal degree	μ(G) = 21
transitive degree	μ_t(G) = 96

A minimal faithful permutation representation — 3 generators on 21 points:

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

GAP

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

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