Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

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

GAP

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

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