Presentation

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

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

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