Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 5 generators on 21 points:

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

GAP

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

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