Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

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

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

GAP

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

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