Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 26 points:

(3,4,7,10)(5,8,9,6)(11,12,15,18)(13,14,17,16)(20,21)(24,25);(3,5,7,9)(4,8,10,6)(11,12,15,18)(13,14,17,16)(19,20,23,21)(22,25,26,24);(3,6,7,8)(4,9,10,5)(11,13,15,17)(12,14,18,16)(19,21,23,20)(22,25,26,24);(3,6)(4,9)(5,10)(7,8)(11,13)(12,16)(14,18)(15,17);(3,6)(4,5)(7,8)(9,10)(11,13)(12,14)(15,17)(16,18);(3,5)(4,8)(6,10)(7,9)(11,14)(12,17)(13,18)(15,16)(19,22)(20,24)(21,25)(23,26);(1,2)

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

gap> G := Group((3,4,7,10)(5,8,9,6)(11,12,15,18)(13,14,17,16)(20,21)(24,25), (3,5,7,9)(4,8,10,6)(11,12,15,18)(13,14,17,16)(19,20,23,21)(22,25,26,24), (3,6,7,8)(4,9,10,5)(11,13,15,17)(12,14,18,16)(19,21,23,20)(22,25,26,24), (3,6)(4,9)(5,10)(7,8)(11,13)(12,16)(14,18)(15,17), (3,6)(4,5)(7,8)(9,10)(11,13)(12,14)(15,17)(16,18), (3,5)(4,8)(6,10)(7,9)(11,14)(12,17)(13,18)(15,16)(19,22)(20,24)(21,25)(23,26), (1,2));
