Presentation

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

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

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

GAP

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

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