Presentation

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

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

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

GAP

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

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