Presentation

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

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

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

GAP

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

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