Presentation

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

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

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

GAP

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

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