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

GAP

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

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