Presentation

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

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

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

GAP

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

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