Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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