Presentation

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

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

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

GAP

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

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