Presentation

minimal degreeμ(G) = 25
transitive degreeμt(G) = 126

A minimal faithful permutation representation — 3 generators on 25 points:

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

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

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