Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 576

A minimal faithful permutation representation — 4 generators on 25 points:

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

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

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