Presentation

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

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

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

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

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